USB Drives Make Medical Conference More Productive

2009-01-03T17:28:00.000-08:00

Lecture materials provided to attendees on flash drives

Thanks to storage solutions from The USB Superstore, medical professionals got something extra at a recent conference in Orlando, Florida.
The seminar featured a roster of leading researchers who spoke on medical advances and cutting edge procedures. Instead of having to take detailed notes during the lectures, attendees were able to listen instead, knowing that all the presentations, notes and support materials were already on hand – preloaded on a flash drive that conference sponsors gave to each attendee.
As most conference, seminar and tradeshow planners know, attendees are often swamped with information that is hard to carry around. Lecture presentations, notes, sales materials and marketing collateral can really weigh a person down during a long day at an event. Not only is this information difficult to cart around, but it also has to be shipped home – and with some airlines charging for a second bag and in some cases the first bag – this can become very expensive.
In the case of this conference, professionals didn’t have to deal with packing around paper. Everything was stored neatly on a branded USB flash drive from The USB Superstore. Convenient and affordable, the drive not only provided attendees with the information they needed, but the drive itself could be used long after the meeting at the office, the lab or at home to transport and store data.
USB promotional items not only save space, but money as well. Compared to the reams of printed materials created for major conferences and tradeshows, a flash drive is inexpensive. Plus, they reduce the amount of paper that needs to be recycled, making them a green promotional giveaway at the same time. It is much more convenient to have all the pertinent information stored on a flash drive, than to carry around a large bag full of brochures and documents.

For conference organizers, flash drives provide a unique opportunity to entice premium sponsors for the conference. Often times, a conference organizer will offer a co-branding opportunity to a premium sponsor whereby the sponsor’s logo is co-branded flash drive with the name of the conference. So, when the attendees leave after the conference, they carry with them all the relevant information from the conference, as well as the premium sponsors logo, all on a functional promotional USB drive that can be used for years to come.

Sharing Music and Video a Snap with USB drives

2009-01-03T17:26:00.000-08:00

Portable drives store favorite songs or video for easy sharing and transfer

In a world filled with iPods and other MP3 players, the ability to store and share music, photos and video with family and friends has not only become fashionable, but commonplace as well.

But did you know that the venerable iPod uses the same storage technology as The USB Superstore’s line of innovative USB-compatible promotional products? If your clients are using their MP3 player to transfer their favorite tunes or videos with others, USB flash drives offer the same convenience at a fraction of the cost.

Perhaps that’s one of the reasons USB products have become such a popular choice among companies seeking to gain an edge in the marketplace. Not only are they finely engineered and affordable, but they are extremely convenient and easy to use.

Using a USB drive is as simple as plug and play. Insert the drive into the USB port on any PC or Macintosh and it will act as a regular storage drive on your system. Move any files you want to store, transfer or share to the drive. Then take your files with you, including your favorite songs, video files, documents and even movies. When you arrive at your destination, reverse the process and all your files are ready to enjoy and use within minutes. The drive is universally compatible, even with computers at an Internet café in a third world country.

As a promotional item, they are highly prized by recipients as well. Unlike a pen, flashlight or coffee mug, a USB flash drive has year-round use and will last for years, too. Recipients enjoy the ability to easily and quickly transfer files using a USB device so much that they continue to use them long after the tradeshow, conference or event they attended.

For businesses, that means effective use of marketing dollars, particularly in a tight economy. As most marketing professionals know, nothing’s worse than spending limited marketing dollars on a campaign, only to have your promotional items end up in a drawer somewhere, or worse, the trash.

A flash drive product never suffers this fate. It will be used day in and day out, putting your logo and marketing message front and center with your prospect or client as they transfer files between home and office or between coworkers, friends and family.

Toshiba Laptops And All-In-One Printers

2009-01-03T17:24:00.000-08:00

Toshiba, a premier electronics manufacturer, has come out with some path breaking technologies in electronics. Its products are well appreciated throughout the globe. Toshiba laptops are also examples of innovative design combined with impeccable practicality.

Laptops are the convenient and user friendly alternatives to the traditional personal computers. The importance of PCs cannot be discounted still. But being portable and lighter in weight, they have become the best friend to everyone, including traveling executives and students alike.

Toshiba laptops have carved a place for themselves in the market. Some are cheaper and affordable but some are niche products meant for a select few. The company produces lightweight laptops, thin laptops and tablet PCs, and the range available in all categories is really vast.

Toshiba lightweights offer sleek and light-weight designs and can be carried easily. They can give you productive hours irrespective of whether you are inside your cabin or in a shop or flying in an aircraft. The Protege A600 series, the R400 series, the R500 series and the U400 are ultra light weight laptops designed for ultimate usefulness. Prices vary according to the specified configuration.

The Tecra R10 series is not only lightweight, but very thin too. They are very useful for a person who is always on the move. The Tecra R10 have all desirable features including webcam, advanced wireless and wide screen LED backlit display, which makes it truly desirable.

Toshiba tablet PCs are one step ahead of others in terms of portability. With all its advanced features like built in Ethernet, Bluetooth, finger print reader and the likes, they are not at all inferior in any count with other models available. For someone who would like to stay connected irrespective of where he is, the satellite pro series is a real gift from god.

No talk of Toshiba laptops can be complete without mentioning the Qosmio series. Often praised as the flagship series of the company, these laptops are veritable beauties but functionality is given an equal importance. They are superb for gaming too. However, they are not cheap by any count. Custom made accessories like battery charger adapter, keyboard protector, carrying case, tablet pen and leather portfolio makes Toshiba laptops easily serviceable and productive.

All-in-one printers are easily compatible with Toshiba laptops. Printing in color as well as black and white, sending faxes, photocopying and even scanning can be done over them. Printers differ in size, color, features and output speed. These factors determine the price. The market is being swamped by an influx of these all-in-one-printers because more and more people are opting to purchase them in order to ensure more productivity, albeit at a considerably lesser cost. Proper care and timely servicing can keep these delicate machines in perfect working conditions for many years.

Apple Computers And Cheap Lcd Monitors

2009-01-03T17:21:00.000-08:00

The computer revolution has reshaped our industries, our services and even our lives. The role Apple computers played and even play now is not second to that of any other manufacturer. The firm, after an initial struggle, has rose to unbelievable heights in recent years and commands a healthy share in the personal computer market.

When you talk of quality products in the information technology, the first name that may pass through your mind would be the Apple Mac series. They are beauties with equal quantity of brains. They are delicate, but strong in functions. They are exquisitely designed, but made for a purpose. With lesser number of software installed, they can perform your jobs faster than cluttered PCs. Apple prefers that you install only the required software and applications. The operating system is also more manageable and does not require registration.

A curious fact about Apple laptops is that they are designed in unusual soft colors while the entire industry are rooting for serious looking black and white colored ones. This added fun to functionality. They are also much versatile. While Mac computers can be run on windows too, other PCs cannot work on Mac Operating System. The use of dual operating systems aids in running more applications than others.

The laptops churned out by Apple are well known for their beauty. The second hand value of these computers is better than others too. But the most likeable feature of Mac series is that you need not change it every two years as in the case of others, because of its futuristic design and amalgamation of applications. They are designed with forethought and purpose.

Apple desktops match their smaller but smarter laptop counterparts in functionality and style. They are perfect options for offices and workstations. However, it is the lightweight, thin and exquisitely carved laptops that almost always hog the limelight.

LCD monitors are the toast of the masses these days. The days of the reliable, hardy, but bulky and harmful CRT screens are gone and the sleek, light weight and less space consuming LCD screens have taken their place. Performance and display quality is also far more superior to CRT monitors. In the course of time, LCD monitors have become impressively cheaper too.

Prices of LCD monitors vary according to the size, resolution, brand name and after sales service. Going for the cheapest with the least features and customer friendliness is not advisable. You have to scout around a little through internet stores and company websites in order to gain a clear real picture and then place your order. Intex, Acer and ViewSonic are renowned manufacturers of reliable and less expensive LCD monitors. You have to be sure about your requirements too. Otherwise you may end up buying a LCD monitor too large or too small to suit your need and available workspace.

How to Decide Whether to Rent Lease or Buy a Computer

2009-01-03T17:20:00.000-08:00

When most people hear talk about “buying” versus “leasing” they usually think of a car purchase or some sort of real estate agreement. However, small business owners have to think about, and decide between, these terms all the time, and relating to almost everything the work with – buildings, vehicles, equipment for the factory floors and computers for the office.

Considering the amazingly low prices for today’s powerful personal computers, one’s first instinct may be to buy a computer without even thinking about it. Of course, you know you are going to use the machine for several years (computers stay reasonable current for the first year, then start aging rapidly) and the fact that you own it can be somewhat reassuring. There are several factors, however, that should prompt you to consider leasing a computer or perhaps even renting one, as opposed to making that impulse buy.

One is never enough

Leasing computers can help a company avoid plunking down so much capital up front. Leasing makes sense when there is a need for an especially powerful, customized, expensive unit, or a number of computers for different departments. This decision can turn the computers into an operating expense, an especially helpful thing if the company is just getting started. Another advantage is that, when directly leasing from a vendor or a manufacturer, businesses do not need to obtain loans from banks – and deal with all the red tape and paperwork that comes with it.

From a financial planning standpoint, leasing makes sense for many businesses, and if the conditions are right, so does renting. Renting computer equipment can be just as good as leasing in the sense that you can always upgrade, fairly painlessly, to the highest quality, greatest power and newest software available. The company renting you the equipment makes their money also assumes the responsibility for repairs and maintenance. Although some leases may differ on service contracts and onsite repairs, if you rent the equipment the owner is still responsible for the technical difficulties occurring throughout the duration of your contract. That is what paying rent is all about. You pay to have predictable functionality and a working asset at all times.

Other factors

If you really want to know what the best course of action is for you business or your personal needs, then do the usual research. There are always plenty of websites that can provide all the facts, crunch all the various numbers and make it worth your while to investigate. Steer clear of the “rent-to-own” dealers, of course, as the offer of “no money down and no credit check” is insufficient to overcome the price you pay down the road. With rent-to-own, it is always bigger than you expect.

If you have special enhancements on your one of your present computers – special internal plug-in cards (PCI), upgraded graphics (AGP) – and have “maxed out” your RAM, you may wish to reconsider replacing that particular unit. It may be difficult to find a lease deal that will allow you to upgrade and replace computer components, and your rental dealer will probably not like that idea much. If you do need customizing, it is best to own your own equipment.

Ask the accountant

If you run a medium-sized or larger firm, and have various departments with various needs, you will have to do a study to determine the actual, real-world, real-time needs of the various personnel. Ask your department managers to research the matter, and then be specific about what they need in the PCs for their respective departments. You can then have your accountant look at the various options – buy, lease, rent – and calculate what mix of these will work for the company as a whole.

It may be that you need to lease new Macintosh computers for your art department, and on an annual basis to stay up with the “state of the art.” Secretaries, word processors and accounting personnel can easily run new, powerful Windows software on lower-cost PCs, and not need upgrading for several years at a time. Purchasing low-end computers would seem a workable solution. If you have engineers and others needing some real computational horsepower, of course, you may even need to leave the realm of PCs and step up to a mini-computer from IBM or Hewlett-Packard. (PCs are actually defined as “microcomputers.”)

The bottom line is different for different companies and their different needs. Often a mix of these methods – buying, leasing and renting – is the ultimate result of a careful study. If you have a small company with just a few employees, of course, your decision should be a bit easier to make. The fact is, with prices so low for power so great, computers are one of the less expensive expenses for companies today, and contribute to the business out of all proportion to their small cost. Whatever strategy you come up with, it should be an affordable one.

A PC in the modern home

2009-01-03T17:18:00.000-08:00

Computers have become an essential part of our day-to-day life. No longer are they just a tool we use when at work. Virtually every household in the UK now owns at least one PC or laptop and many homes now have more than one. With the introduction of wireless routers and broadband a few years ago ‘PC Recovery’ have found that many people would now rather be without their television than their computer. A spokesperson for ‘PC Recovery’ said “Typical PC users these days will use their computer for a wide variety of tasks. From emailing their friends and family to booking cheap flights online. We have found many people will store all their photographs and music on their computer as well as any important documents such as a CV or letter to their bank”

With the increase in home PC usage it stands to reason that more and more problems are going to arise. “It’s no longer a case of just removing a virus or upgrading someone’s RAM” said the spokesperson. “Many families now have home networks with several computers and laptops involved. As well as wireless printers and network storage devices and they want to make the most of their hardware whether it is a laptop or a desktop PC.”

As computers are able to take care of more and more tasks for us computer engineers are finding themselves doing a wider variety of tasks than in the past. Apart from the obvious things such as fixing a broadband problem or removing a virus from a computer, they now find themselves doing things such as setting up home games consoles on the internet i.e Xbox 360 or PS3, or installing a customer’s mobile phone or MP3 player. “Times are changing” said the spokesperson. “And with it our engineers are finding they have to adapt and keep abreast of new technology and new advancements.”

Without doubt the most popular advancement in recent years would be the wireless network. Throughout the United Kingdom and in particular southeast England there are hundreds upon thousands of wireless hotspots, many of which are free. “If you drive into any town center in Essex or Kent you are now able to access the internet from many available hotspots” revealed the spokesperson “Libraries, fast food restaurants, cafes and even hotels are now only too happy to offer this service free of charge in order to encourage potential customers to use their facilities” The problems arise when people access private wireless networks that have not been secured. “This can cause a great deal of problems and security issues for the owner of the private network. This can potentially be very damaging as in the wrong hands this access could lead to bank details and personal files be extorted from the owner’s computers.

So while the new age of wireless is incredibly useful and makes it much easier for us to keep in touch with each other and indeed our online pursuits we should all take care and if necessary have our home networks checked by someone professional before it is too late. “We have seen too many people fall foul of stolen identity just by leaving their home network unsecured” said the spokesperson “So it does pay to have your system and network checked by someone professional and reputable every so often, even just for your own peace of mind.”

How to 'Download' Your Old Computer to the Highest Bidder

2009-01-03T17:16:00.000-08:00

When you think trash, you surely don't think about your old, trusty personal computer. But that's exactly what will become of it when you make the inevitable move toward your next laptop or desktop. And, yes, buying a new computer is inevitable, considering the pace at which computer technology zips along. Just think-about a handful of years ago, a fast microprocessor for a laptop was at 233 MHz. Now you're looking at about at least 2 GHz! That's Giga, with a G.

So eventually, you will want a computer that can handle the latest software, the latest games, and the latest interactive Web sites, and then you'll have to throw away your old computer, right? Wrong. Try selling your used computer instead. Throwing out your computer is one of the worst things you can do. For one, your computer may be useful for someone out there, even if just for scraps.

Trashed computers and other digital equipment also make up one of the fastest growing, and most dangerous, new trash "categories" out there in your neighborhood landfill. On one hand, computers are generally bulky and made of plastic and other materials that won't be breaking down in a landfill for the next few million years. What's more, other materials in your old computer are highly toxic to the environment, like mercury, lead and cadmium. They're so toxic that their actually name in the waste-management field is "toxics."

You don't have to be a techie or a scientist to understand the danger in that-nor the benefits of selling your computer. On the Internet, there are a vast number of auction and classifieds sites, some better than others, where you can "download" you computer to a worthy buyer.

Before you boot up your replacement laptop or high-performance PC, however, be sure you read and compute the following tips. These tips will help you avoid the crashes and shutdowns that befall the computer seller who doesn't do his homework first.

Hold onto all of the operating system and software manuals that came with your old computer. This will add value to your sale, not to mention it will make you a trusted seller for offering up these helpful books to the buyer.

Erase all personal information from the hard drive. And we're not just talking about simply putting stuff in the "trash bin." It's extremely important to purge all data from your computer's memory repository, even from invisible backup files on the hard drive. If you're not sure how to do this, ask your IT expert at work or a techie friend for advice. You don't want the next user to have access to your bank accounts, old e-mails, and other private info, do you?

Uninstall any application from the hard drive that you'd like to use on your next computer, keeping the installation disk and the software serial number for yourself. When it comes to software, the manufacturers made sure that you never really own software, you license it. So you don't get free reign to keep software on multiple computers. You only get one license, so you need to bring your licensed version with you to your new computer.

Do your homework on your computer's worth. Just like you would for a car, check around at other classifieds and auction sites to see what other people are selling your make and model for.

Be sure you want to truly get rid of old faithful. You may be able to repair your old laptop rather than buy a new $2,000 Centrino model. Or you may be able to add RAM memory and a new hard drive to your four-year-old desktop rather than invest in a new $3,000 multimedia masterpiece. In other words, do a thorough cost-analysis of what it would take to rebuild your old computer, versus what it would cost to sell it and buy a new one. And check your heart too. You might be surprised just how attached you are to your old faithful.

Once you go through these steps, you are prepared to make your move and sell, sell, sell. And then, of course, you'll be ready to start on a whole new list of steps-for buying a new computer. But that's a topic for another article!

Cheap Computers

Building Cheap Computers in 3 Easy Steps

Just a decade ago, the only people who put computers together were those individuals who possessed an extensive technical background. Advancements in technology have eliminated some of the complexities in how computers work. This change has resulted in average people who have a basic understanding of computers being able to build a system themselves. Whether you are interested in building computers to establish a new hobby or to start a business, you can so in only a few easy steps and on a shoestring budget.

The first step in building cheap computers is to determine the route you want to use to build systems. You basically have three choices when considering building cheap computers: build a system from scratch, expand on a bare bones computer, or upgrade an existing system. Building a system from scratch can be a rewarding experience. However, it is not for everyone. If you are impatient or are intimidated by mechanical tools, you are better to choose one of the other two options.

Regardless of the method you choose, you will follow three basic steps:

1. Plan
2. Assemble
3. Test

The planning phase of your project involves determining the specifications for the computer you want to build. Once you know this information you can start shopping for parts that meet those specifications. Your main considerations should be
hard-disk, memory, and CPU (central processing unit). The harddrive is important because it determines how much information you are able to store on the computer. While you could build a computer with a harddrive smaller than 2 GB (gigabytes), it is not recommended.

The harddrive and memory work together. The amount of memory you place in your computer will directly affect how the system is able to complete the different processes that you request when using the system. If you have no idea what size hard-drive and the amount of memory you need, you should consider the type of operating system you intend to load on the system. You can consult the manufacturer of your hard-drive or review the information on Cheap-Computer-Guy.com, which features a list of minimum harddrive and memory requirements for various operating systems, and use this information as a guide.

The equipment presented in this article includes the basics of a computer system. Of course, nowadays people want far more than the basics and you undoubtedly feel the same way. There are optional components available that you may want to add to your systems, which include CD or DVD drives, a modem or other communication component for Internet connectivity, or a video graphics card.

Once you have decided on the specifications of the computer you want to build, you are ready to assemble the system. In addition to detailed information about the parts you will need to build your computer, cheap-computer-guy.com includes step-by-step instructions for assembling a cheap do-it-yourself computer.

When you have finished assembling the computer, you will then need to test to make sure that the system boots and that all components are functioning properly. Once you have completed all these tests you will have built your own cheap computer.
You can find detailed information about planning, assembling and testing computers at the Cheap-Computer-Guy.com website.

Spyware And/Or Adware

2009-01-03T17:14:00.002-08:00

9 Warning Signs You Might Be Infected With Spyware And/Or Adware

FACT: Chances are your machine is hosting spyware. There are currently over 78,000 Spyware and Adware programs on the Internet that can affect your PC.

Here are 9 warning signs you should be aware of, if any of them pertain to you then your PC is most likely infected:

If you start you Internet browser and the homepage that pops up is not the one that has been set by you. You then change it back to what you want and then it goes back to something you didn't set again. This is one of the more common features and ways to tell that you have been taken over by some sort of spyware and that you should rid your system of it immediately.

If you get pop-ups that have been personalized with your name on them or you begin to receive pop up ads while you are not even connected to the Internet or don't have a browser open. This is one of the more annoying ways that your system will let you know that you have something other than normal operating in your system.

You start receiving very expensive phone bills that have you placing many calls to 900 numbers that you never heard and ones that have hefty per-minute rates. Spyware takes over your phone line due to the connection that you have in conjunction with that phone service, whether dial-up or broadband.

You enter a searchable item into your required Internet toolbar or address bar and then all of sudden an unapproved searching system handles your search. More infamous items are infected with stuff such as Mysearch Bar and other spyware type search engines that only take you to their approved sites.

Another sure fire way to know that you have spyware operating on your system is that you have view your favorites list and you have favorite sites in their that you did not put in yourself and have found that other sites you put there are no longer found. You delete these items but they always show up again in your favorites.

Your system begins to run slower than normal. If you are a updated Windows OS user you pull up your task manager system information screen and see that your system is running at 100%, then you are infected with spyware because your system always needs a little free space in order to process information, which is why your system slows down when you have spyware on it.

At a time when you are not doing anything online, the send or receive lights on your dial-up or broadband modem blink just as wildly and lively as when you are online downloading a file or surfing the Internet. Also, your network icon on your screen will be flashing rapidly showing you that you are working on receiving and sending information from your system at a very rapid rate. This is the job of spyware here to send and receive information to your system without telling you.

A search toolbar or other browser toolbar appears even though you didn't request it or install it. Your attempts to remove it fail, or it comes back after removal. Parts of spyware registry files hide themselves in your system under aliases and unless you find all of them and remove them, then they will never leave your system, causing them to show up over and over again.

And the final sign is: Everything appears to be running normal but the most deceptive and devious spyware leaves no tracking information for you to find it anyway. This is the sure way to get you to check your system on a routine and regular basis so that you are sure you have no signs of an infection.

When not on his soapbox, Andrew Wroblewski is doing battle with the thousands of spyware programs that can affect you via his anti-spyware and spyware removalwebsite: http://spyware.pcwash.com where you can get a FREE spyware scan of your computer system.

Keylogger Software

2009-01-03T17:14:00.001-08:00

Keylogger Software - Parents Benefit

When online, children are completely out of the parental control and parents can't actually find out what their children do when online.

Banning children from computers or allowing using it only when parents are supervising the process is not a good solution. Besides producing a negative impact on relations with you child, this also makes it harder for your offspring to compete with other children, as the Internet these days gives certain social and academic advantages. However, the Internet should be filtered, there's absolutely no doubt. So what is the solution?

More and more parents realize they shouldn't impose any direct control over their child's online activity thus trying to find out what their children are doing online. This task finds an easy solution in special keylogger software. Such software monitors computer activity and saves the report in special files so that the parents can later check it out and make conclusions. Keyloggers usually show what applications were used on the controlled computer, what sites a child visited and what he actually wrote to his online pals. There are enhanced search and sorting options, so any suspicious activity can be easily traced.

There are quite a lot of keyloggers currently available on the market. Quality depends and so does the price. Keyloggers are usually very simple to install, setup and use and require no special skills from the user. Most of them cost around $30, though there are more sophisticated species that may cost a little bit more. Keylogger software usually operates in the invisible mode and children don't know their parents have an eye on them.

However, this last feature often comes as an obstacle for the parents. They think that keylogging their children' online activity equals to spying and that such harsh supervision in not required for their beloved ones. Well, even if your child is very smart and kind, he or she is still a child so there is still a threat that they can make a wrong choice. And the consequences may be horrible. There are online predators that try to gather information about children in various chat rooms to take hostile actions against them in the real life. Even though children who realize they should keep their private information really private, can reveal some bits of information to a predator, who will then stick the facts together and find out what he needs.

Keylogger software often comes as the only solution for the parents with children who have the opportunity to access the Internet on a regular basis. Parents should know what happens with their children and try to prevent the possible danger. And the Internet, regrettably, carries a lot of danger with it, so keylogging software may really help to notice the problem long before it actually comes to life.

Computer Cool

Keep Your Computer Cool

If the computer after several hours' use suddenly rebooted and does not show any sign of system failure, there could only be one thing. The computer is overheating.

Unknown to many, (especially those who are not into technological stuff) the computer could generate a large amount of heat when it is in use. Adding video or sound cards could also add more heat generation from your computer.

The temperature inside the computer or laptop that has high-powered processors that runs with multiple applications reaches one hundred forty (140) degrees.

The more drives, memory and even colored lights stuffed in today's CPUs and laptops, the less space there is for internal air circulation. Combine that with poor exhaust or surrounding ventilation, and systems slow, applications run poorly, or the computer could reboot to cool itself down, or crash altogether.

The popularity of cheap computers is fast increasing. People are drawn to buying the cheap computers but they are not aware of the reductions made just so to meet the demand.

One of these reductions is the size as well as the effectiveness of cooling fans on the computer. As the computer gets warmer, the computer speed also gets slower.

With the proper cooling device in the computer, rest assured that the performance of the computer would be better. It could also extend the life of the computer, motherboard and the processor.

Cooling products help drop the temperature of the CPU and its components by circulating, dissipating, cooling and pulling air from a desktop or laptop computer.

Some fans mount in the front drive bays of computers, while others slip into PCI slots to suck air out the back. Copper or aluminum "heat sinks" mount atop the processor to cool that device itself.

When buying a new computer, visit a retailer and touch the computer case to see how hot it gets. Consider adding additional fans to the PCI slots or atop the processor.

Other cooling tips include cleaning dust away from the CPU's fan, or opening the unit and using a can of compressed air to blow dust off the components.

Keep the CPU off the floor, and install filters atop the fans, to reduce dust, pet fur or other debris from getting into the unit. A small electrical fan aimed to blow across the CPU also can help disperse heat and cool the unit.

Keep the computer in a location where air can circulate freely. Keeping the tower in a desk cabinet, leaving the doors open or removed to aid circulation also helps air to circulate inside the computer.

For general office cooling, a flat-panel monitor, or LCD, can reduce the amount of heat generated, as compared to a traditional CRT monitor.

Laptop heat is especially common. Many road warriors, teleworkers and home office workers place the laptop literally upon their laps to work.

This not only can block exhaust fans, but can trap and build heat. Laptop pads dissipate heat by either elevating the unit from the surface, or by using fans to help draw heat away from the device.

Many slot coolers are being marketed today. There are two things that you have to consider before buying one. The intake of fresh cool air is very important. Case temperature drops with the intake fan in the case. T

he position of the fan is the other. It has to be positioned one slot away from the AGP card. The extra space would help the airflow inside the computer. This way the computer heat would be lessened.

Computer Virus Scan

2009-01-03T17:11:00.000-08:00

Computer Virus Scan, Your 24/7 Dutiful Guard

Computers nowadays will not last without the installations of a good anti virus software. It is recommended that a frequent computer virus scan be done to ensure that your computer has not been infected with a virus. Most of us have probably experienced computer defaults caused by a virus attack and feel that you are not safe enough from hackers. So, keep your computer safe from these dangerous virus threats.

Install Computer Virus Scan software and protect your personal data from hackers, detect and remove spywares, adwares and web dialers. Virus scan softwares also restore your computer if it is already infected. They will detect the infections and have them removed, deleted or quarantined.

Imagine having a malicious program destroying your files and computer in seconds? These could be files that you have worked so hard for. So why not secure your computer? Nobody wants his hard disk destroyed, personal information stolen and files erased.

With the growing number of viruses - worms, trojans and other hazards that can easily infect your computer, protecting your PC has never been more important. Especially now that computers has been given a more important role in our daily lives.

The availability of virus scan softwares and the development of new programs in the light of this problem put an ease to many of the computer owners. Virus scan destroys all viruses which could have penetrated into the system mostly, cleaning up takes only but a few seconds.

While at first install it would do a thorough computer virus scan to ensure that there is no virus hiding anywhere in your pc. After that it would do occasional computer virus scans to maintain the cleanliness of your computer.

Computer virus scan programs also detect potentially unwanted applications like spyware, adware, web dialers and more.

Advanced antivirus technology detects and removes all latest versions of worm, email, download and other computer viruses, including Sobig, Lovsan (MSBlaster), Bugbear, Palyh, Fizzer, Klez, Sircam, Nimda, CIH, "I love you" virus, "Anna Kournikova" virus, Hahaha, Badtrans, Vbs funlove letter, Melissa and many other worm, back door and Trojan Horse viruses.

With a computer virus scanner on duty, you will almost never contract a virus. You can surf the Internet safely, read your emails and download files without being worried about viruses.

After installing a computer virus scanner, it will act as a 24/7 guard to your computer. Tirelessly it will guard your computer against attacks from viruses and preventing harm from other malicious software.

The background scanner will operate continuously, watching for viruses as you are using your computer for everyday tasks. You do not have to do anything. In the software, a computer virus scanner will perform this function and do the entire job automatically, in the background, ensuring the safety of your computer. Or, if you wish, you can configure it to schedule, run and manage your own scan operations.

The scanner starts when you start your computer, and stays in memory until you shut it or your system down. The scanner also includes optional features that keep your computer from connecting to dangerous Internet sites.

If you plug-in permanently or just connect periodically to the Internet, computer virus scan softwares automatically checks for the latest virus definitions, patches and fixes -- then updates itself automatically. This is your first line of defense against computer viruses. In some anti virus software they can also be your second, third and fourth.

Bookmark Managers: Programs vs. Web Services

2009-01-03T17:07:00.000-08:00

The rapid development of the World Wide Web in recent years has led to an explosive growth of information on the Internet. Our contemporary lifestyle would be unimaginable without access to such a super-abundant cornucopia of valuable information and web surfing has now become an everyday occupation for even the most diverse sections of society.

This rapid expansion of web resources raises some new issues for all of us. How could you possibly remember; after a long search, the address of that crucial web page? How will you be able to return to the page without repeating a tedious web search through hundreds and thousands of pages?
The answer is obvious, you need a program that will allow you to easily create and manage a database of web resources. Of course, this database must be quick, intuitive and convenient to use.

One way to resolve this problem is to use your web browser's bookmarks feature. Bookmarks are a popular term for the lists of web page links stored in web browsers, although they are called 'Favorites' in Internet Explorer. These web browser bookmark systems have some severe limitations. For example, each bookmark list will only be compatible with a specific web browser. If you use several different web browsers you will have to manage the bookmark system in each one. Web browser bookmark lists may become cumbersome to use when your bookmark list grows beyond a few items. Important features missing from web browser bookmark systems include:
• Powerful search functions
• Synchronization of bookmarks between different computers
• Detection and automatic deletion of duplicate bookmarks
• Checks for availability of bookmarked web pages.
Specialist programs and web services that store and organize bookmarks are now available and they offer a comprehensive solution to these problems. They are called bookmark managers or bookmark organizers (in this article both terms have the same meaning). The difference between online (web-based) bookmark managers and standalone bookmark managers is in the location of the stored bookmark database and in the way that the database is accessed. Web services called 'online bookmark managers' store the user's bookmarks on their remote servers and their bookmarks may be accessed from any browser. A standalone bookmark organizer is simply a program which runs on your local computer. It stores the bookmark database on a hard disk and allows access through its own built-in interface.

Here are some examples of web-based bookmark managers:

iKeepBookmarks.com - www.ikeepbookmarks.com

LinkaGoGo - www.linkagogo.com

Murl - murl.com

You can find more links to online bookmark managers here:
http://dmoz.org/Computers/Internet/On_the_Web/Web_Applications/Bookmark_Managers/

Bookmark management software can be found here:

Link Commander - www.resortlabs.com/bookmark-manager/linkcommander.php

Linkman - www.outertech.com/index.php?_charisma_page=product&id=5

Powermarks - www.kaylon.com/power.html

Any software catalog will contain plenty of links to bookmark managers. For example: www.snapfiles.com/shareware/misctools/swurlorg.html

Offline and online bookmark managers each have relative advantages and disadvantages due to their differing methods of database storage and access.

An online bookmark manager does not depend on any particular computer. If you have an Internet connection you can access your bookmarks from any computer in the world. You don't need to synchronize the bookmarks on your home/work PC or notebook because they will all access the same bookmarks database. With an online bookmark manager you can access your bookmarks even when you are in an Internet cafe! Another advantage is that most of them are free. They will cost you time, though, because you access your bookmarks via an Internet connection. More importantly, most of the web interfaces are not as convenient as software based bookmark managers and don't have so many useful features. For example, they can't search for and delete duplicate database items. Here are some of the other potential disadvantages of using online bookmark managers:

1) You risk losing all your bookmarks if, for some reason, the web service closes down.

2) There is a danger of unauthorized access to your private bookmarks because your bookmark manager server may not be secure against hackers.

The advantages and disadvantages of offline bookmark managers are almost exactly opposite to those of online bookmark managers and will be discussed next.

Any offline bookmark manager is tied to the computer on which it is installed. It stores your bookmarks in a database (which usually has its own proprietary format) that is located on one of the hard drives. To use your bookmarks on several computers you will need to install the program on each computer and find a way to synchronize the bookmark databases. Most of the currently available bookmark organizers do have a database synchronization feature. Also, there are now devices with high data transfer speeds (e.g. flash drives) that can store an independent bookmark database and allow it to be shared between several computers.

Another disadvantage of bookmark manager software is the price. There are some free programs out there, but they don't have a great number of features and technical support is often weak or unavailable. The programs that require payment are inexpensive, though, usually costing from $20 to $40. The user licenses of such programs will normally allow you to install the programs on all of your computers.

In my opinion, the disadvantages of standalone bookmark managers are minimal compared to their advantages. The location of both the program and database on the same computer guarantees you fast access to your bookmarks and high security from hacker attacks. The convenience of the program interface and the number of useful features are limited only by the power of the computer and the skills of developers.

So, how should you organize your bookmarks? Should you use an online or offline bookmark manager? I don't think there is a definite answer. It all depends on your preferences and working habits. If mobility is your priority, if you travel often and wish to access your bookmarks no matter where you are and from any computer, then you should consider an online bookmark manager. If speed, ease of use, security and functionality is most important to you then an offline bookmark manager might be a better choice.

How a Registry Cleaner Can Eliminate the Blue Screen of Death

2008-12-16T19:17:00.000-08:00

Computers are incredibly useful and they are constantly helping us streamline our lives. Without them, everything we do, from paying bills to ordering holiday gifts, would involve extra steps and extra time. But, computers can make our lives difficult as well—especially when they generate error messages we don’t understand. Even worse than error messages, the widely-feared Blue Screen of Death (BSOD) can abruptly change the way we see our computer, making it a burden in an instant. If you have ever been in the midst of working on a project for work or school on your computer, and have seen the feared BSOD, you know what this feels like. The operating system generates an error that says “fatal error” and you suddenly think your computer—and your project—are gone. While the “fatal error” sounds deadly, there’s no need to worry. Armed with the right information and the right tool, you can bring your system back to life. And, once you’ve revived it, the system will be running faster than ever. Knowing what the Blue Screen of Death is and how to avoid and repair it is key. Once armed with this knowledge, your operating system will be less overwhelming to you. The BSOD error is generally caused by errors in the Windows system registry. The registry is a directory within your Windows operating system that stores settings and options.

Holding an abundance of information, the registry acts as a closet. Imagine all the items you add to your closet over the course of a year. Over time, your closet becomes disorganized and you can’t find things you need. The process of finding things in your closet slows down dramatically. The same is true with the Windows system registry. Over time, the registry becomes cluttered with entries and begins to function poorly, sometimes even generating frightening errors. One common error in the system registry that leads to slowdowns and to the Blue Screen of Death is the DLL error. Before learning about the DLL error, it is important to understand what DLL files are. They are central to all applications and programs and they enable shared files to link up with each other. Without DLL files, a program’s files would not be able to communicate in order to execute the program. DLL files are easy to identify because they end in the .dll extension. Before you encountered the Blue Screen of Death, it is possible that your system generated an error regarding a DLL file. Whether your BSOD was caused by a DLL error or another issue, the answer lies within your system’s registry. There are two solutions then for the Blue Screen of Death.

First, you can manually investigate your system’s registry and manually repair any errors. This can be very time-consuming. There is a second, easier solution.

You can download a registry cleaning tool to scan and clean your Windows operating system registry. A popular and efficient registry cleaner is RegCure. This registry cleaner will scan your registry and remove any unneeded entries that are causing slowdowns and errors. The first step is visiting RegistryRepairProgram.com. There, you’ll be able to download a free scan of your system’s registry. From there, you can choose whether you want to use RegCure to clean your registry. If you elect to use RegCure, your BSOD errors will disappear. In addition, any other system errors you have experienced will disappear as well. Most important, your system will return to functioning like new, and you will notice the change in speed. Sorting through your registry manually takes time, but using a registry cleaner is the best thing you can do to fix annoying, or in the case of the Blue Screen of Death, overwhelming system errors. If you use RegCure on a regular basis, you will never experience a last minute BSOD crisis again.

Network Camera Video Surveillance for Towns and Cities

2008-12-16T19:13:00.000-08:00

Expansion of towns and cities is always a good thing, but it also brings with it potential problems such as increased crime. One way to help defend against increases in crime in your city or town is to employ the use of a network camera / IP camera video surveillance system. This can prove to be a vital part of your municipality's security infrastructure.

Benefits for Municipalities

Crime can be a horrible for a city, especially a growing one. The use of video surveillance can help cut down on crime, thus making the city safer and more attractive both for new residents and for new businesses. This is a good thing for everyone in town.

IP cameras used in public areas can also make these areas safer. In some cities, parks are known as havens of crime and many residents tend to avoid them, rendering these public areas almost useless. Through the proper use of a video surveillance system this problem can be curtailed, cutting down on the crime in these areas and making them safe for resident use once again.

Network Cameras for Video Surveillance

When dealing with a very large area, such as a town or city, network cameras can have a real advantage over traditional CCTV cameras. Network cameras, also known as IP (Internet Protocol) cameras come with built-in web servers and their video feeds are accessible via network. This means that no actual physical connection between IP cameras and monitoring stations need to exist: as long as the monitoring station is connected to the same network as the camera, then feeds can be viewed. This is an excellent way to handle a number of different cameras all from a single location, or at least allow a single location access to a number of different cameras, even if the cameras also have more local monitoring stations.

Another benefit of network cameras is enhanced quality. These cameras take video in a digital format, and depending on the camera resolution can often be much higher than that found in analog cameras. This gives your town's police force or security personnel a better image of the happenings on in the town, thus make it easier for them to perform their duties.

The use of advanced IP camera software can also be a great boon to a town's video surveillance system. With the use of this software, alarm systems can be set into place, or automatic notifications can be sent to officers on patrol, etc., based on certain parameters programmed into the software. This is a great tool which can be used in a number of different ways in various situations.

Installing a Municipal Video Surveillance System

It can often be tricky to install a municipal video surveillance system. Depending on property laws in the area, it will probably be best not to have it done by the town, but to work with local businesses and residents to have them set up their own cameras. For public areas such as parks, this will of course be done by the municipality itself, but for downtown and other areas where most if not all property is private, cooperation between town and businesses will be needed. You might wish to consider an incentive plan for businesses that cooperate with implement video surveillance systems

Obviously an entire town cannot be covered with cameras, so you will need to prioritize what areas should be covered. The busiest areas such as downtown or other shopping areas, public parks, etc. should definitely be considered. You should also look at the crime rates in town, see what areas are the most vulnerable to crime and concentrate on these areas as well.

How to Choose Reliable CD DVD Replication Services

2008-12-16T19:11:00.000-08:00

CD/DVD duplication service is a serious business that needs a serious solution, but must not be expensive. There are plenty of companies advertising their services over the Internet and through local store offering DVD replication and CD duplication, but only few can really deliver the quality and assurance one is looking for. Finding these companies is not hard. All you need is a little investigation and you’re good to go in outsourcing your needs.

What should be the criteria when choosing the right company to handle your CD/DVD duplication need? Doing these tasks on your end may sound impossible so we need to let experts do it for us. Companies with expertise on this field can provide a client with best results while spending the least amount.

First thing we need to consider is the company’s reputation. We must only entrust our business needs to reputable companies to get assurance of the quality of service and output we can get. A reputable company offering CD DVD replication services has everything to lose when it fails to provide a client with satisfactory level of service and an excellent quality output. A company’s reputation serves as our bargain when allowing them to do the job.

Fast turn around with high percentage of accuracy should also be among the company’s concerns. Numbers of companies in existence are offering DVD replication and CD duplication services providing clients with fast turn around time. This is a good indication that a company can handle task that needs immediate completion. These companies are also confident to make this assure because they have state-of-the-art technological equipment that can cater a client’s need.

The next important thing that a client should consider would be the price. With the tight competition on CD duplication or DVD replication services, prices are way affordable compared to those that were offered years ago. These services may require good quality result, but it should not be expensive. It is very important for a client to compare prices offered by companies offering CD/DVD duplication services before making the deal.

Support center should be available 24/7. Yes! As a client, you must look for a company’s support center. This will serve as the mediator between you and the company. In case there is a need for slight changes with your CD duplication requirements or any thing that you want to inform the company, you can easily do these things by contacting their support center.

Aside from the basic CD duplication or DVD replication services several companies offer added services to their clients. These include labeling and packaging. For promotional purposes, right labeling can boost a client’s business and may serve as additional promotional materials. Packaging services on the other hand lessen the burden of the client when thinking of how orders will be shipped.

DVD duplication service is a blessing to most of us especially musicians who do not have enough funds to support wide scale product of materials. This is the best alternative for companies in need of CD or DVD as informational materials for business promotion and employee awareness programs.

Things you should know when you take your Laptop on the road

2008-12-16T18:46:00.000-08:00

You need to keep an eye on your laptop. If you take it out of the house, make sure the bag is closed all the way, zipped shut. It is easy for a thief to swipe your laptop out of your bag on the street or subway if they can see it. Then, as you go throughout your day make sure you keep the strap over your shoulder opposite the side of you body. This makes it much harder for a thief to snatch it from you. If you place it on the ground while paying for coffee or at the airport ticket counter make sure you place it between your legs and squeeze your ankles around it.

When go out to get some work done and you set your laptop up at a coffee shop. Be sure to use a laptop security cable. Attach it to anything you can. It doesn’t have to be attached to the building or floor, as long as it’s noticeable. A thief is not going to drag a chair out of the coffee shop and down the street.

You need to attach the lock as soon as you sit down as you don’t know when you are going to have to get up quickly to run to the bathroom, or to get more sugar or another coffee.

If you make it a habit of locking your laptop every time you take it out, you are much less likely to be a victim of theft.

This includes locking it at the office and at home. You would be surprised at how many laptops get swiped from desks in large office towers during lunch when there are not many people around. And if your house should happen to get broken into, the TV can be replaced, and you can live without it for a day or two, but if your laptop is taken, then all your work, documents and pictures etc.. are gone! Even if you are smart enough to back up, the odds are that you didn’t back up the minute before your laptop is stolen so you are going to be out some data. Then there is the downtime, now you have to spend half a day computer shopping, arguing with the insurance company buying and installing new software (the cost may not be covered by insurance) and not to mention that your deductible may be too high to even bother making a claim.

On top of that, you may end up struggling with a new operating system that you are not familiar with for weeks, and dealing with loosing all your settings and bookmarks.

A lot of people say “my laptop is old, I hope someone steals it!”… We all would like to get a newer faster laptop, but you don’t need to be “forced” into a new upgrade in the middle of working on a new project.

Then this all leads to the data on your laptop. You could have personal information on your laptop including names, address, Social Insurance Numbers or Social Security Numbers, credit card numbers, bank accounts, medical information, legal information etc…

The privacy laws will hold YOU responsible for the damages those people receive. If fraud is committed against someone because you lost your laptop with their information, if they lose money or their credit is damaged, then you are responsible for their loss.

How to Configure SSH (Secure Shell) for Remote Login on a Cisco Router

2008-12-16T18:44:00.000-08:00

Prior to the introduction of SSH in the Cisco IOS, the only remote login protocol was Telnet. Although quite functional, Telnet is a non-secure protocol in which the entire session, including authentication, is in clear text and thus subject to snooping.

SSH is both a protocol and an application that replaces Telnet and provides an encrypted connection for remote administration of a Cisco network device such as a router, switch, or security appliance.

The Cisco IOS includes both an SSH server and an SSH client. This document is concerned only with the configuration of the SSH server component.

Prerequisites

Software

The SSH server component requires that you have an IPSec (DES or 3DES) encryption software image from Cisco IOS Release 12.1(1)T or later installed on your router. Advanced IP services images include the IPSec component. This document was written using c2800nm-advipservicesk9-mz.123-14.T5.bin.

Pre-configuration

You must configure a hostname and a domain name on your router. For example:

router#
router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
router01(config)#hostname router01
router01(config)#ip domain-name soundtraining.net

You must also generate an RSA keypair for your router which automatically enables SSH. In the following example, note how the keypair is named for the combination of hostname and domain name that were previously configured. The modulus represents the key length. Cisco recommends a minimum key length of 1024 bits (even though the default key length is 512 bits):

router01(config)#
router01(config)#crypto key generate rsa
The name for the keys will be: router01.soundtraining.net
Choose the size of the key modulus in the range of 360 to 2048 for your General Purpose Keys. Choosing a key modulus greater than 512 may take a few minutes.

How many bits in the modulus [512]: 1024
% Generating 1024 bit RSA keys ...[OK]

Finally, you must either use an AAA server such as a RADIUS or TACACS+ server or create a local user database to authenticate remote users and enable authentication on the terminal lines. For the purpose of this document, we'll create a local user database on the router. In the following example, the user "donc" was created with a privilege level of 15 (the maximum allowed) and given an encrypted password of "p@ss5678". (The command "secret" followed by "0" tells the router to encrypt the following plaintext password. In the router's running configuration, the password would not be human readable.) We also used line configuration mode to tell the router to use its local user database for authentication (login local) on terminals lines 0-4.

router01(config)#username donc privilege 15 secret 0 p@ss5678
router01(config)#line vty 0 4
router01(config-line)#login local

Enabling SSH

To enable SSH, you must tell the router which keypair to use. Optionally, you can configure the SSH version (it defaults to SSH version 1), authentication timeout values, and several other parameters. In the following example, we told the router to use the previously created keypair and to use SSH version 2:

router01(config)#
router01(config)#ip ssh version 2
router01(config)#ip ssh rsa keypair-name router01.soundtraining.net

You can now log on to your router securely using an SSH client such as TeraTerm.

Viewing SSH Configurations and Connections

You can use the privileged mode commands "view ssh" and "view ip ssh" to view SSH configurations and connections (if any). In the following example, the SSHv1 configuration from a Cisco 871 router is verified using "show ip ssh" and a single SSHv1 connection is displayed using the command "show ssh". Notice that we did not enable SSHv2 on this router, so it defaulted to SSH version 1.99. Also note in the output of the "show ssh" command that SSH version 1 defaults to 3DES. SSHv2 supports AES, a more robust and efficient encryption technology. SSHv2 is also not subject to the same security exploits as SSHv1. soundtraining.net recommends the use of SSHv2 and disabling a dropback to SSHv1. Enabling SSHv2 disables SSHv1. This example is included only to demonstrate backwards compatibility:

router04#
router04#show ip ssh
SSH Enabled - version 1.99
Authentication timeout: 120 secs; Authentication retries: 3
router04#
router04#show ssh
Connection Version Encryption State Username
2 1.5 3DES Session started donc
%No SSHv2 server connections running.
router04#

You can also use the command "debug ip ssh" to troubleshoot SSH configurations.

Of mp3 and Online games

2008-12-16T18:35:00.000-08:00

There are two things in life that I am very passionate about: mp3s and online games. I absolutely begged for my father to buy me a brand new laptop and to subscribe to a fast internet connection so that I could have my fill of downloading and playing. “Pa, please I really need a brand new laptop!” “How can I do my research and homework and stuff?” This is the argument that would fill every dinner conversations. I always attack from this-is-for-my-school angle. I find that it is the most effective argument to use. (Take note of that guys! It may come in handy for you someday.) I had also added some puppy dog look to that to add some more convincing power. I knew that soon he’ll give in, but, of course, I did some extra chores around the house before that. If you saw some really shiny and spotless house back then, that was ours.

We finally bought this cool Lenovo laptop with fingerprint scanning, webcam, Dolby digital sound, wireless fidelity (wifi), Bluetooth, DVD combo writer and all the bells and whistles that would put the old Apollo spacecraft to shame. (Well, that is what the sales person told us. I really would not know for sure.) As long as that Laptop has speakers and can connect to the Internet, I really do not care if it contains the fastest Intel processor or the latest NVIDIA GeForce. (whatever those are) I remember that I pressured pa to drive faster on the way home so that I could finally use my new laptop. I got a long sermon from him about road safety and being a responsible driver because of that.

Ok now that I have told you the very boring story of how I got my laptop, let me tell you about my two passions. My family has always been music lovers. We have a huge collection of cds from different genre. Pa likes to listen to classical music. (you know, Mozart and stuff) Ma likes old songs especially The Carpenters, Bread and Abba. (I think these are 1970s groups.) Brother likes his noisy music while I like R and B and hiphop. To save money, I used to borrow my classmates’ cds, rip them and save them into mp3 format. I listen to them for hours and hours and hours.

But my main interests are online games. I have been a fan of those engrossing games at yahoo, but lately, I have been a Bratz games fanatic. Bratz games? Yes, you heard me right. Bratz games. Those games that are inspired by the hit dolls Bratz. Bratz games have over twenty games to choose from. They do not have as many as those found in yahoo but it does not mean that they are less interesting. I tried all the Bratz games in the site and everything there was very fun for me. The characters are so cute, I would have hug them if they were real toys.

Know the Essential Skills to Become an Ethical hacker

2008-12-16T18:32:00.000-08:00

Computer security has become a major cause of worry for businesses and governments all over the world. Though internet has made e-commerce possible, helped in advertising products and services to millions of people, it has also led to the rise of criminal hacking. Due to this, a growing number of companies and governments are turning to ethical or white-hat hackers to get them out of the problem.

A certified ethical hacker tests the security of the systems, look for viruses and rectify the problems pertaining to the network security. But in order to become en efficient ethical hacker, you need to have competent skills along with the right attitude.

Programming skills
The knowledge of programming languages is a mandatory. You should learn the technique of C, C++, Python, Java, Perl and Lisp.

As a beginner, you can start by learning Python which is less complicated as compared to other languages but at the same time challenging enough. It is well-documented and well-designed. Afterwards, you can learn C, Lisp, Perl and java.
It is important to learn Perl as it is used extensively for web pages and system administration.

All these languages have different approach to programming, and by acquiring the knowledge of each one of these would make you much more efficient hacker. Each language has its own significance and at the end of the day you would benefit by learning each one of them.

UNIX
You can’t become a hacker unless you learn and understand UNIX. After all UNIX is the platform on which the Internet is built upon. Though there are other platforms, it is not possible to read the code or modify them. However with UNIX you can read how the operating system is written and modify it. Hence, learn to hack on open-source UNIX by getting a Linux or BDS-UNIX installed on your personal computer and practice on it daily for hours.

HTML
To become a hacker, you should know how the World Wide Web functions. And having knowledge of web is not just restricted to how to use the browser. You should make efforts to learn and write HTML.

Usage of English
In order to become an efficient ethical hacker, you need to have a good command over the English language, as it is the English language which dominates the Internet. All the books on hacking come in English language. Hence concentrate to improve on this part too.

Apart from all this, read lots of books on hacking. The more you read; the better. Buy books or enrol in some libraries and take them on rent. And don’t hesitate in experimenting. To become a white-hat hacker, you need to have the curiosity to learn about new things.

In fact, you can also take up hacking course. There are several reputed institutes which offer certified hacking courses with theoretical as well practical training. Getting proper training from prestigious institutes would benefit you a lot and help you in becoming a professional, certified ethical hacker.

Configuring a Site-to-Site VPN Between Two Cisco Routers

2008-12-16T18:29:00.000-08:00

A site-to-site virtual private network (VPN) allows you to maintain a secure "always-on" connection between two physically separate sites using an existing non-secure network such as the public Internet. Traffic between the two sites is transmitted over an encrypted tunnel to prevent snooping or other types of data attacks.

This configuration requires an IOS software image that supports cryptography. The one used in the examples is c870-advipservicesk9-mz.124-15.T6.bin.

There are several protocols used in creating the VPN including protocols used for a key exchange between the peers, those used to encrypt the tunnel, and hashing technologies which produce message digests.

VPN Protocols

IPSec: Internet Protocol Security (IPSec) is a suite of protocols that are used to secure IP communications. IPSec involves both key exchanges and tunnel encryption. You can think of IPSec as a framework for implementing security. When creating an IPSec VPN, you can choose from a variety of security technologies to implement the tunnel.

ISAKMP (IKE): Internet Security Association and Key Management Protocol (ISAKMP) provides a means for authenticating the peers in a secure communication. It typically uses Internet Key Exchange (IKE), but other technologies can also be used. Public keys or a pre-shared key are used to authenticate the parties to the communication.

MD5: Message-Digest algorithm 5 (MD5) is an often used, but partially insecure cryptographic hash function with a 128-bit hash value. A cryptographic hash function is a way of taking an arbitrary block of data and returning a fixed-size bit string, the hash value based on the original block of data. The hashing process is designed so that a change to the data will also change the hash value. The hash value is also called the message digest.

SHA: Secure Hash Algorithm (SHA) is a set of cryptographic hash functions designed by the National Security Agency (NSA). The three SHA algorithms are structured differently and are distinguished as SHA-0,SHA-1, and SHA-2. SHA-1 is a commonly used hashing algorithm with a standard key length of 160 bits.

ESP: Encapsulating Security Payload (ESP) is a member of the IPsec protocol suite that provides origin authenticity, integrity, and confidentiality protection of packets. ESP also supports encryption-only and authentication-only configurations, but using encryption without authentication is strongly discouraged because it is insecure. Unlike the other IPsec protocol, Authentication Header (AH), ESP does not protect the IP packet header. This difference makes ESP preferred for use in a Network Address Translation configuration. ESP operates directly on top of IP, using IP protocol number 50.

DES: The Data Encryption Standard (DES) provides 56-bit encryption. It is no longer considered a secure protocol because its short key-length makes it vulnerable to brute-force attacks.

3DES: Three DES was designed to overcome the limitations and weaknesses of DES by using three different 56-bit keys in a encrypting, decrypting, and re-encrypting operation. 3DES keys are 168 bits in length. When using 3DES, the data is first encrypted with one 56-bit key, then decrypted with a different 56-bit key, the output of which is then re-encrypted with a third 56-bit key.

AES: The Advanced Encryption Standard (AES) was designed as a replacement for DES and 3DES. It is available in varying key lengths and is generally considered to be about six times faster than 3DES.

HMAC: The Hashing Message Authentication Code (HMAC) is a type of message authentication code (MAC). HMAC is calculated using a specific algorithm involving a cryptographic hash function in combination with a secret key.

Configuring a Site-to-Site VPN

The process of configuring a site-to-site VPN involves several steps:

Phase One configuration involves configuring the key exchange. This process uses ISAKMP to identify the hashing algorithm and authentication method. It is also one of two places where you must identify the peer at the opposite end of the tunnel. In this example, we chose SHA as the hashing algorithm due to its more robust nature, including its 160-bit key. The key "vpnkey" must be identical on both ends of the tunnel. The address "192.168.16.105" is the outside interface of the router at the opposite end of the tunnel.

Sample phase one configuration:
tukwila(config)#crypto isakmp policy 10
tukwila(config-isakmp)#hash sha
tukwila(config-isakmp)#authentication pre-share
tukwila(config-isakmp)#crypto isakmp key vpnkey address 192.168.16.105

Phase Two configuration involves configuring the encrypted tunnel. In Phase Two configuration, you create and name a transform set which identifies the encrypting protocols used to create the secure tunnel. You must also create a crypto map in which you identify the peer at the opposite end of the tunnel, specify the transform-set to be used, and specify which access control list will identify permitted traffic flows. In this example, we chose AES due to its heightened security and enhanced performance. The statement "set peer 192.168.16.25" identifies the outside interface of the router at the opposite end of the tunnel. The statement "set transform-set vpnset" tells the router to use the parameters specified in the transform-set vpnset in this tunnel. The "match address 100" statement is used to associate the tunnel with access-list 100 which will be defined later.

Sample phase two configuration:
tukwila(config)#crypto ipsec transform-set vpnset esp-aes esp-sha-hmac
tukwila(cfg-crypto-trans)#exit
tukwila(config)#crypto map vpnset 10 ipsec-isakmp
% NOTE: This new crypto map will remain disabled until a peer
and a valid access list have been configured.
tukwila(config-crypto-map)#set peer 192.168.16.105
tukwila(config-crypto-map)#set transform-set vpnset
tukwila(config-crypto-map)#match address 100

The crypto map must be applied to your outside interface (in this example, interface FastEthernet 4):

tukwila(config)#int f4
tukwila(config-if)#crypto map vpnset

You must create an access control list to explicitly allow traffic from the router's inside LAN across the tunnel to the other router's inside LAN (in this example, the router tukwila's inside LAN network address is 10.10.10.0/24 and the other router's inside LAN network address is 10.20.0.0/24):

tukwila(config)#access-list 100 permit ip 10.10.10.0 0.0.0.255 10.20.0.0 0.0.0.255

(For more information about the syntax of access-control lists, see my other articles on creating and managing Cisco router access-control lists.)

You must also create a default gateway (also known as the "gateway of last resort"). In this example, the default gateway is at 192.168.16.1:

tukwila(config)#ip route 0.0.0.0 0.0.0.0 192.168.16.1

Verifying VPN Connections

The following two commands can be used to verify VPN connections:

Router#show crypto ipsec sa
This command displays the settings used by the current Security Associations (SAs).

Router#show crypto isakmp sa
This command displays current IKE Security Associations.

Troubleshooting VPN Connections

After confirming physical connectivity, audit both ends of the VPN connection to ensure they mirror each other.

Use debugging to analyze VPN connection difficulties:

Router#debug crypto isakmp
This command allows you to observe Phase 1 ISAKMP negotiations.

Router#debug crypto ipsec
This command allows you to observe Phase 2 IPSec negotiations.

USB Flash Drives As a Sales Vehicles

2008-12-16T18:27:00.000-08:00

Give Your Customers A Little Something Extra…

If I could sell you a brand new $50 note, for the bargain price of $20, you'd bite my hand off, wouldn't you?

Well, I can! Sort of...

You see, Promotional USB flash drives aren't just a way to keep your customers happy, to build or sustain your brand image or get a new product out there. They can also drive sales. And of course, more sales means more money.

Why not try offering a free USB drive with every order over $50 this month? Or a free USB Drive if you recommend a friend and they in turn spend over $50? Perhaps you could offer a range of incentives, matching memory size to the amount spent? Stand out from the crowd by using promotional gifts in a different way, to actually increase the bottom line now, rather than just building for the future.

Of course, the question has to be "Will offering a free USB Drive make my customer spend more than they usually would? Or spend money when they'd usually wouldn't?"

To answer the first part, I have four words for you. Amazon Super Saver Delivery. How often have you wanted a $5 book, but ended up spending $15 or more, just to qualify for the chance to have it delivered free? The answer for me has to be "More often than I'd admit". Now if they can make someone triple their spending to qualify for a $2 saving, what could a USB Drive make someone spend? Far more than it would cost you to buy it in, I'd wager.

As for the second part, how often have you been browsing through a catalogue, walking down the street or surfing the internet, not intent on buying anything, when the offer of a free muffin with every coffee, a free cookie with every sub of the day or free songs with the latest iPod has drawn you in?

Meanwhile, even the customers that would have bought enough to qualify for the free Promotional USB Drive aren't a loss. After all, it's still going to build their loyalty to you, make them feel appreciated, and acts as a brilliant way to deliver a new catalogue or showcase a new product launch to them by additionally preloading something onto the Drives

Imagine that once your valued customers have made a larger-than-expected purchase, received a complimentary flash drive, and whatever information you chose to pre-load onto it. Perhaps there is a contest or promotion you’ve been thinking about running. Utilizing USB flash drives as a means of information dissemination keeps your message at your customers fingertips…literally.
USB Drives really are Win-Win.

As for the second part, how often have you been browsing through a catalogue, walking down the street or surfing the internet, not intent on buying anything, when the offer of a free muffin with every coffee, a free cookie with every sub of the day or free songs with the latest iPod has drawn you in?

USB Drives Make Medical Conference More Productive

2008-12-16T18:23:00.000-08:00

Lecture materials provided to attendees on flash drives

Thanks to storage solutions from The USB Superstore, medical professionals got something extra at a recent conference in Orlando, Florida.
The seminar featured a roster of leading researchers who spoke on medical advances and cutting edge procedures. Instead of having to take detailed notes during the lectures, attendees were able to listen instead, knowing that all the presentations, notes and support materials were already on hand – preloaded on a flash drive that conference sponsors gave to each attendee.
As most conference, seminar and tradeshow planners know, attendees are often swamped with information that is hard to carry around. Lecture presentations, notes, sales materials and marketing collateral can really weigh a person down during a long day at an event. Not only is this information difficult to cart around, but it also has to be shipped home – and with some airlines charging for a second bag and in some cases the first bag – this can become very expensive.
In the case of this conference, professionals didn’t have to deal with packing around paper. Everything was stored neatly on a branded USB flash drive from The USB Superstore. Convenient and affordable, the drive not only provided attendees with the information they needed, but the drive itself could be used long after the meeting at the office, the lab or at home to transport and store data.
USB promotional items not only save space, but money as well. Compared to the reams of printed materials created for major conferences and tradeshows, a flash drive is inexpensive. Plus, they reduce the amount of paper that needs to be recycled, making them a green promotional giveaway at the same time. It is much more convenient to have all the pertinent information stored on a flash drive, than to carry around a large bag full of brochures and documents.

For conference organizers, flash drives provide a unique opportunity to entice premium sponsors for the conference. Often times, a conference organizer will offer a co-branding opportunity to a premium sponsor whereby the sponsor’s logo is co-branded flash drive with the name of the conference. So, when the attendees leave after the conference, they carry with them all the relevant information from the conference, as well as the premium sponsors logo, all on a functional promotional USB drive that can be used for years to come.

LF Radio NTP Servers: How to Decode the DCF-77 Time Broadcast

2008-12-16T18:14:00.000-08:00

The DCF-77 radio time and frequency transmission is broadcast from Mainflingen, Germany. The DCF-77 signal can be used by timing equipment to provide an accurate time reference. Computer systems, such as NTP time server systems, which provide a precise time reference for networks can utilise the broadcast as an accurate external source of time. This article describes how the DCF-77 signal can be decoded to provide an accurate time reference for NTP time servers and other computer applications.

Before describing the format of the transmission, it's worth mentioning a little about the history of the transmitter. The German National Standard time and frequency radio broadcast, call sign DCF-77, has been in operation since 1959. The broadcast is currently maintained by T-Systems, a sub-division of the German Telecoms company Deuche Telecom. Precise timing information for the broadcast is generated from caesium atomic clocks maintained by the German National Physics Laboratory. The transmittor has a power rating of 50W, which can be received up to 1900 km from Frankfurt. Reception can easily be obtained throughout much of central and northwestern Europe. The transmission is broadcast as an amplitude-modulated, pulse-width encoded data signal. Precise timing information is continuously broadcast, repeated each minute. Data is broadcast as 59 pulses, one pulse each second, each pulse representing a data bit. Each pulse represents a data bit, either a binary one or binary zero. A one hundred millisecond pulse represents a binary zero, while a two hundred millisecond pulse represents a binary one. The pulses can be decoded at the end of the minute into date and time information.

Time and date information is encoded in the DCF-77 transmission as Binary Coded Decimal format. Data bits are encoded into the transmission as follows. Data bits in the range 1 to 14 are reserved for future developments. Bit 15 indicates the transmitter in current operation - primary transmitter or backup transmitter. Bit 16 represents the announcement of daylight saving change. Bit 17 indicates whether daylight saving is currently in use. Bit 18 indicates standard time and is the inverse of bit 17. Bit 19 indicates that an imminent leap second is to be inserted. Bit 20 indicates the start of time and date information. Bits 21-27 represent BCD encoded minutes. Bits 29-34 represent BCD encoded hours. Bits 36-41 represent BCD encoded day of month Bits 42-44 represent BCD encoded day of week Bits 45-49 represent BCD encoded month of the year. Bits 50-57 represent BCD encoded year. Finally, parity bits are inserted into the encoded data as follows. Parity bit 28 covers bits 21-27. Parity bit 35 covers bits 29-34. Parity bit 58 covers bits 36-57.

To summarise, the DCF-77 time transmission is a reliable and accurate source of time from NTP server systems and other computer timing applications. The signal can be generally be received indoors close to the NTP time server itself, thus reducing installations costs. Additionally, the straight-forward encoding of timing date within the transmission enables simple implementation into NTP server software. Indeed, the Linux NTP software distribution for includes a standard reference clock driver for the DCF-77 transmission.

How to Decide Whether to Rent Lease or Buy a Computer

2008-12-16T18:12:00.000-08:00

When most people hear talk about “buying” versus “leasing” they usually think of a car purchase or some sort of real estate agreement. However, small business owners have to think about, and decide between, these terms all the time, and relating to almost everything the work with – buildings, vehicles, equipment for the factory floors and computers for the office.

Considering the amazingly low prices for today’s powerful personal computers, one’s first instinct may be to buy a computer without even thinking about it. Of course, you know you are going to use the machine for several years (computers stay reasonable current for the first year, then start aging rapidly) and the fact that you own it can be somewhat reassuring. There are several factors, however, that should prompt you to consider leasing a computer or perhaps even renting one, as opposed to making that impulse buy.

One is never enough

Leasing computers can help a company avoid plunking down so much capital up front. Leasing makes sense when there is a need for an especially powerful, customized, expensive unit, or a number of computers for different departments. This decision can turn the computers into an operating expense, an especially helpful thing if the company is just getting started. Another advantage is that, when directly leasing from a vendor or a manufacturer, businesses do not need to obtain loans from banks – and deal with all the red tape and paperwork that comes with it.

From a financial planning standpoint, leasing makes sense for many businesses, and if the conditions are right, so does renting. Renting computer equipment can be just as good as leasing in the sense that you can always upgrade, fairly painlessly, to the highest quality, greatest power and newest software available. The company renting you the equipment makes their money also assumes the responsibility for repairs and maintenance. Although some leases may differ on service contracts and onsite repairs, if you rent the equipment the owner is still responsible for the technical difficulties occurring throughout the duration of your contract. That is what paying rent is all about. You pay to have predictable functionality and a working asset at all times.

Other factors

If you really want to know what the best course of action is for you business or your personal needs, then do the usual research. There are always plenty of websites that can provide all the facts, crunch all the various numbers and make it worth your while to investigate. Steer clear of the “rent-to-own” dealers, of course, as the offer of “no money down and no credit check” is insufficient to overcome the price you pay down the road. With rent-to-own, it is always bigger than you expect.

If you have special enhancements on your one of your present computers – special internal plug-in cards (PCI), upgraded graphics (AGP) – and have “maxed out” your RAM, you may wish to reconsider replacing that particular unit. It may be difficult to find a lease deal that will allow you to upgrade and replace computer components, and your rental dealer will probably not like that idea much. If you do need customizing, it is best to own your own equipment.

Ask the accountant

If you run a medium-sized or larger firm, and have various departments with various needs, you will have to do a study to determine the actual, real-world, real-time needs of the various personnel. Ask your department managers to research the matter, and then be specific about what they need in the PCs for their respective departments. You can then have your accountant look at the various options – buy, lease, rent – and calculate what mix of these will work for the company as a whole.

It may be that you need to lease new Macintosh computers for your art department, and on an annual basis to stay up with the “state of the art.” Secretaries, word processors and accounting personnel can easily run new, powerful Windows software on lower-cost PCs, and not need upgrading for several years at a time. Purchasing low-end computers would seem a workable solution. If you have engineers and others needing some real computational horsepower, of course, you may even need to leave the realm of PCs and step up to a mini-computer from IBM or Hewlett-Packard. (PCs are actually defined as “microcomputers.”)

The bottom line is different for different companies and their different needs. Often a mix of these methods – buying, leasing and renting – is the ultimate result of a careful study. If you have a small company with just a few employees, of course, your decision should be a bit easier to make. The fact is, with prices so low for power so great, computers are one of the less expensive expenses for companies today, and contribute to the business out of all proportion to their small cost. Whatever strategy you come up with, it should be an affordable one.

A PC in the modern home

2008-12-16T18:10:00.000-08:00

Computers have become an essential part of our day-to-day life. No longer are they just a tool we use when at work. Virtually every household in the UK now owns at least one PC or laptop and many homes now have more than one. With the introduction of wireless routers and broadband a few years ago ‘PC Recovery’ have found that many people would now rather be without their television than their computer. A spokesperson for ‘PC Recovery’ said “Typical PC users these days will use their computer for a wide variety of tasks. From emailing their friends and family to booking cheap flights online. We have found many people will store all their photographs and music on their computer as well as any important documents such as a CV or letter to their bank”

With the increase in home PC usage it stands to reason that more and more problems are going to arise. “It’s no longer a case of just removing a virus or upgrading someone’s RAM” said the spokesperson. “Many families now have home networks with several computers and laptops involved. As well as wireless printers and network storage devices and they want to make the most of their hardware whether it is a laptop or a desktop PC.”

As computers are able to take care of more and more tasks for us computer engineers are finding themselves doing a wider variety of tasks than in the past. Apart from the obvious things such as fixing a broadband problem or removing a virus from a computer, they now find themselves doing things such as setting up home games consoles on the internet i.e Xbox 360 or PS3, or installing a customer’s mobile phone or MP3 player. “Times are changing” said the spokesperson. “And with it our engineers are finding they have to adapt and keep abreast of new technology and new advancements.”

Without doubt the most popular advancement in recent years would be the wireless network. Throughout the United Kingdom and in particular southeast England there are hundreds upon thousands of wireless hotspots, many of which are free. “If you drive into any town center in Essex or Kent you are now able to access the internet from many available hotspots” revealed the spokesperson “Libraries, fast food restaurants, cafes and even hotels are now only too happy to offer this service free of charge in order to encourage potential customers to use their facilities” The problems arise when people access private wireless networks that have not been secured. “This can cause a great deal of problems and security issues for the owner of the private network. This can potentially be very damaging as in the wrong hands this access could lead to bank details and personal files be extorted from the owner’s computers.

So while the new age of wireless is incredibly useful and makes it much easier for us to keep in touch with each other and indeed our online pursuits we should all take care and if necessary have our home networks checked by someone professional before it is too late. “We have seen too many people fall foul of stolen identity just by leaving their home network unsecured” said the spokesperson “So it does pay to have your system and network checked by someone professional and reputable every so often, even just for your own peace of mind.”

Comparing Motherboards for the Upcoming Core i7 Processors

2008-11-30T03:16:00.000-08:00

In the next few months, more and more buzz will be generated for new motherboards. That's because with the launch of Intel Core i7 processors, only new motherboards with the X58 chipset can be used. In other words, if an enthusiast wants to upgrade a CPU, the motherboard has to be upgraded as well.

A lot of information has been released by technology news websites on various motherboards such as the ASUS P6T Deluxe OC Palm,Intel DX58SO, MSI Eclipse and EVGA's X58 SLI motherboard. In order not to be overwhelmed by the plethora of articles on these motherboards, it may be a good idea to be clear headed and focus our attention on the crucial elements.

Crucial element 1: Speed

The overall speed of the computer system depends on the multiplier values of the system. For example, you can achieve higher performance if you tweak the multiplier values of the CPU or the memory. Overclocking enthusiasts will be most interested to know if the system can run reliability at the overclocked values.

In this area, the ASUS P6T motherboard offers an extra in the 2.5" LCD displays that presents system configuration information, overclocking data, etc. This is useful for overclockers who want to tweak and monitor the system while it runs.

Crucial element 2: Graphics

The graphics of a computer system is another major component to take into consideration. Many software applications require a lot of graphics processing power to run smoothly. This includes professional software, such as video and audio editing software that performs a lot of zooming, panning, modeling of 3D objects, etc. Many 3D games also require powerful graphic processing for best effects.

Enthusiasts should check whether the motherboard has SLI (Scalable Link Interface) support. SLI is a technology developed by nVidia, and it's used for multi-GPU processing. Not all motherboards support this feature because manufacturers are required to pay a royalty to nVidia if they want to offer support for SLI.

Since SLI is meant for intensive graphics processing, only those who need it for business applications or gaming need to consider having this feature.

Crucial element 3: Memory.

The memory on a system affects the overall speed of the computer. With powerful processors, enthusiasts have to make sure that there won't be a bottleneck when it comes to memory. Having insufficient memory could mean that the system will run at substandard performance.

Motherboards with the X58 chipset offer support for triple channel DDR3 memory kits. Various memory manufacturers from Taiwan and China have already released memory kits that are timed perfectly for the Core i7 processors.

Enthusiasts should pay attention to the number of slots available. For instance, the ASUS P6T motherboard has 6 memory slots, allowing a max memory of 12 GB. Other motherboard options may have only 3.

As far as the motherboard is concerned, there are various editions available. Of course, one can expect the high-end editions to be much more costly. However, enthusiasts can still enjoy the increased performance at an affordable price if options are selected wisely.

Registry Needs Cleaning - Main Reason Computers Run Slowly

2008-11-30T03:15:00.001-08:00

When using your computer and adding or removing files or programs,fragments of data are left on your hard drive in the Windows registry. Over a period of time this accumulates and causes the registry to become overloaded with unwanted data. This the most prominent cause for slow running,freezing and crashing problems.

Spyware or adware is installed unknown to you by third parties who want to track your computer usage and benefit from this knowledge.This also uses up your computer's resources and can be another cause of slow running. Free antispyware programs can be downloaded on the internet and do an excellent job.

Needless to say viruses are a major problem if they infect your machine. Every computer which is used on the internet must have an antivirus program installed or infection is certain. A firewall is good protection but is not enough on it's own. Free antivirus programs are readily available on the internet and do a very good job of protecting your computer.

When your computer registry accumulates a large amount of unwanted data entries it becomes bloated and clogged. The operating system finds it difficult to navigate through all the junk in order to find the data needed to run your computer. The result is a slow running computer,freezing,and the occasional complete crash. If not corrected this will steadily get worse.

Your computer registry is a databank of information which the operating system uses to run the computer and programs. All Windows operated computers since Windows 95 have a registry. This is the most common source for computer problems involving slow running,freezing and crashing.

If your registry has become corrupted by unwanted material the best solution is to remove these entries by cleaning the registry. You can use the regedit function which is installed on all Windows computers,for this purpose,to do this yourself. With the regedit function you can remove any unwanted entries from the registry. Use great caution here however as many registry files are absolutely necessary for running your machine. If you remove any of these entries you can cause problems.

Unless you are very knowledgeable about the contents of the registry,and can recognise the essential entries which must not be removed,you should not attempt to edit the registry yourself. It is better to be safe and to use an online application to clean your registry safely and easily.

Several register cleaner applications can be found online. The most popular applications will all clean your registry reasonably well. However as with most things some are better than others and there are considerable differences in ease of use,safety and availability of email help when you need it.

Notebook Computer Displays

2008-11-30T03:14:00.000-08:00

When it comes to laptop computers, the choice of display size is one of the most important considerations you have to make. It is just as important as ram size, hard drive size, and processor speed. The display size will also heavily factor into the overall weight of the notebook computer. A larger display size means a larger physical footprint, which is more or less desireable depending on whether you need an ultraportable, mainstream, or gaming style computer. The most important factor, however, is your comfort level. A smaller screen (ultraportable size) may mean great mobility, but none of that is helpful if text or pictures appear uncomfortably small.

Types Of Displays

Due to increasing demand, more and more manufacturers are making widescreen displays available as well as standard displays. Standard TV's and computer displays utilize a 4:3 (or 1.33:1) aspect ratio, including notebook computers.

Standard 4:3 Aspect Ratio

The standard 4:3 aspect ratio has been in use by notebook computer displays for a long time and is offered in several screen resolutions:

- 800 x 600 (SVGA) - 1024 x 768(XGA) - 1400 x 1050 (SXGA+) - 1600 x 1200 (UXGA)

Resolutions higher than 1024 x 768 can only be found in displays sized 14 inches and above. Ultraportable notebooks with displays sizes under 14 inches are unable to have high-resolution displays.

Widescreen Display

Using a 16:9 or 16:10 aspect ratio, widescreen displays can generally display about 25% more content than a standard display. Computer manufacturers offer several size displays from 8.9", 10.6", 11.1", 12.1", 13.3", 14", 15.4", to 17". These sizes are popular now with even larger sizes in the pipeline.

When used for entertainment, DVD movies in particular, a widescreen display is in its element as it shows widescreen movies in their intended 16:9 aspect ratio. This means a bigger picture, more comfort and thinner or no black bands on either side of the picture.

The widescreen display also makes it easier to edit and view panoramic images and may eliminate horizontal scrolling on your computer altogether. When editing images of normal 4:3 aspect ratio, you can simply place your GUI tools/utilities in the unused spaces on either side of an image. In any case, a widescreen display can help you increase work and play efficiency.

Another benefit of the widescreen display is evident when it comes to serious work - the ability to display two windows side by side and to drag and drop (or copy n' paste) data without having to switch windows is invaluable.

Common Widescreen Display Resolutions

Here are the common resolutions found in :

1280 x 768 And 1280 x 800

1280 x 768 (16:9.5) and 1280 x 800 (16:10) are the two most common resolutions used in 10.6, 12.1, 13.3, 14, and 15.4-inch entry-level widescreen notebook computers. They provide about a 25% more onscreen content than standard screens with 1024 x 768 resolution.

1366 x 768

This resolution provides a 16:9 aspect ratio and a great widescreen DVD movie experience without any black bands above and below the picture.

1440 x 900

This resolution 16:10 is found only in 17" notebooks and is positioned as entry level in 17" widescreen notebooks.

1680 x 1050

This is currently the mainstream resolution, also 16:10, for 17" widescreen notebook computer displays. There is a 35% increase in onscreen content compared to normal 17" screens using a standard display resolution of 1280 x 1024.

1920 x 1200

At this time this is the highest for 17" widescreen notebook displays, and provides a 75% increase in onscreen content when compared to a standard 17" screen of 1280 x 1024 resolution. A great display for movies and gaming, however this relatively heavy laptop computer has tradeoffs in mobility.

Create Your Audio CDs from MP3 Files

2008-11-30T03:11:00.002-08:00

Digital files like music files are now popularly stored in digital systems like computers. The computer as a storage system requires a certain format from the music file that will be stored and mp3 format is the most widely used format. People choose to store database of music using the mp3 format in their computer. However, like any other file creating mp3 backup is also essential. Mp3 backup creation can prevent file crashing, file corruption and other troubles you wouldn't want to happen in the first place. So what needs to be done then? Back up your mp3 files by converting the files into audio CDs.

The Answer: Creation of Audio CDs from MP3 Files

Since converting your mp3 files or your music files into an audio CD is essential and the most convenient way and smartest way to do. Though the converted audio CD can serve as the backup files of your mp3 files, it is still more appropriate to say that the mp3 files converted into audio CDs is not exactly the real process of making backup files.

This is why there is a need for CD burning software that is being used to burn or create an audio CD along with the CD writer drive. How is CD burning or creation of audio CD from mp3 files done? To make it simple, you as the user just have to compile your mp3 playlist that contains the mp3 files or music of your choice. Then, you will store the music files with the help of the CD burning software.

What are the burning procedures in creating your audio CDs from mp3 files?

Before you even get disoriented, you should be aware first that the burning procedures are easy and undemanding. To start with the burning procedure, the mp3 files like your music need to be converted into another format file called compact disc audio or CDA. However, and for the record the CDA conversion process happens internally which means it is run by the software program. The display result of the CDA operation is not shown for the sake of the user, you just have to be aware of it.

Nero: the Most Popular CD Burning Program for MP3 to Audio CD Conversion

And for the most popular CD burning program, Nero is always on top of the list. Nero is always the choice of many users because of its capabilities to take over all burning procedures, including unknown conversion processes and options for customization intended for advances users. An example of the Nero customized options is its simplified audio editor. The audio editor can offer advanced options that consist of noise reduction, stereo widening, file splitting, and sound equalization.

For the record, not all CD burning software can offer the same advanced features since other situations require manual processing prior to CD burning. Other software is employed like the audio editing software to do the manual operation. But the good thing about this is that, software other than Nero burning program is made available online. In fact, beneficial editing functions for mp3 files actually lead to the so called normalization process.

The Normalization Process: Another Essential Procedure in Audio CD Creation

The normalization process involves the smoothening out of the volume spikes that exist in various tracks contained in the CD. Normalization guarantees the loudness and sound variation of music or mp3 files when played. The results of the editing procedure need to save in WAV format which in turn will be burned in the CD.

There are times that mp3 files can be stored or burned into another format known as compact disc recordable or the CD-R format. Though CD-R format can be applied by the users, certain digital systems, especially the advanced and modern CD players, do not support the form. The incompatibility of the CD-R format will not let the files like music files to be played at all.

MP3s Don't Necessarily Require Various CD Formats

Though it is not fundamental to convert mp3 files into a new and different format, the files can be burned directly to audio CDs without undergoing any conversion process. So if the WAV format will be executed, there will only be 10 songs as compared to 120 songs that will be saved when mp3 files will be stored and compressed in just a CD via CD burning. The stored files in the audio CD format can be played using other digital players because the CD format is compatible with both CD and DVD formats.

Tips on Buying Desktop Computer

2008-11-30T03:11:00.001-08:00

Whether your old computer is shot or you have never bought a computer on your own before, you may be feeling a little bit nervous about the whole thing. Buying a computer represents putting down a fair chunk of your hard earned money, and you may be nervous about getting a computer that isn’t a great fit for your needs.

The truth is, getting a good desktop computer that suits you is easier than you think, and by simply keeping the following tips in mind, you’ll be able to find the perfect computer that will keep you happy for years to come.

* Know what you want your computer for

Think about how you use your computer. Are you someone who only uses a computer for its word processing ability, or do you prefer to stay up to date on the latest games.

Maybe you are someone whose entertainment is largely focused around your computer; all of your communication and your movies are kept on your computer. By keeping a clear idea of what you need your computer for, you will be able to get the right machine.

* Know what RAM is

RAM stands for Random Access Memory, and you will find that what it does is affect the speed with which your computer “thinks,” that is, processes action. If you are only using your computer for things like surfing online or writing, you’ll find that a RAM of 512 MB is okay, though 1GB is ideal.

You’ll find that this size will give you room to expand or grow if you want to later on, but that it’s not so big that you are wasting your money. If you are going to be gaming, or doing advanced computer programming with your unit,, you will of course want more.

* Don’t worry so much about hard drive space

Your hard drive space generally refers to the amount of information that you can keep on your computer, ranging from written work to audio and visual media.

You’ll find that if you download a lot of videos that this can be eaten up fast, but in desktop, you’ll find that it is very easy to add some more. Remember that while you do have a finite amount of space that it is all in how you use it.

* Online or from the store?

You’ll find that ordering online is actually a lot cheaper, but keep in mind that you should have a clue about what you are looking it. If you choose to build a computer yourself, you’ll find that it is much easier to get the parts online.

At a store, though, you will find that you can often take the time to look over the specs, speak with a sales representative and take a look around to see what else is available. It really depends on what you are comfortable with.

If you are looking to buy a desktop computer, remember that you really need to think about what you want it for. Once you have the function decided upon, it is very easy to figure out what machine will be perfect for you.

How Can I Fix ActiveX Errors?

2008-11-30T03:10:00.000-08:00

There is nothing worse than browsing the web—researching airfare for your next vacation, buying tickets for tonight’s show, watching a news video—and then getting interrupted with an error message such as, “Your current security settings prohibit running ActiveX controls on this page. As a result, the page may not display correctly.” Or you could be checking your email or downloading music when an ActiveX error pops up. When these errors occur you may be left frustrated and asking yourself, “What is ActiveX, and how can I fix it?” It turns out that your Pc is not really in need of an ActiveX repair, but a registry repair.

What is the Registry?
The registry is like a low-level operators manual for your Windows operating system. It stores information and settings for basic functions—its almost like a dictionary. Every time you right click on your mouse for example, your computer accesses the registry, which will “define” the action and tell the computer what to do. The registry has information that is native to the operating system, but this dictionary can also be added to or overwritten. In the event you install a new mouse for example, new information might be added, or old settings might be replaced. An easy way to know if your registry has been altered in any way is if you are required to re-boot your computer (typically after installing new hardware or software).

What is Active X?
Computers allow us to do a lot more than just click a mouse however, and that’s where ActiveX comes in. Certain programs like Microsoft Office, Windows Media Player, or Internet Explorer require very advanced functions, and are constantly changing and upgrading. One way to look at it is that these programs have advanced so much beyond the basic building blocks, they no longer speak English. In order to access the basic information contained in the registry (which they need to function), they need a translator. ActiveX is that translator. ActiveX accesses information stored in the registry, and communicates it to these programs so they can function at the next level.

Problem:
ActiveX is often hard at work behind the scenes accessing the registry for information. These efforts usually go unnoticed and go off without a hitch, but you may be unlucky enough to experience an error. Some common errors are:

• When ‘Downloading ActiveX Control’ your Internet Explorer freezes
• Runtime Error ‘429′: ActiveX Component Can’t Create Object
• Your current security settings prohibit running ActiveX controls on this page. As a result, the page may not display correctly.

These errors are frustrating but one can see why they might occur. What’s happening is that ActiveX is trying to access the registry, or “dictionary.” But the dictionary has become overcrowded and altered beyond recognition. Picture this: There are now two or three different definitions listed instead of only one. Someone has pasted over sections with new information, and the original text can’t be found. Pages have gone missing, and information has been misfiled. The dictionary is now virtually useless. You are now in desperate need of registry repair.

Solution:
One solution would to go out and buy a new computer (i.e. purchase a new dictionary). Not only is this not a realistic solution financially, but all that new and valuable information would be lost. The ideal solution is to flip through and edit the entire dictionary, page by page. Fortunately, this solution is offered via a software called Reg Cure. Reg Cure is a registry cleaner that uses the most sophisticated technology available to analyze your registry for missing, obsolete, and corrupt entries. It is a safe, effective way to fix your PC registry errors. You can download Reg Cure and scan your computer for free at RegistryRepairProgram.

Don’t let ActiveX errors keep you from accessing your favorite programs. Reg Cure offers you an easy solution to a common problem. There is no need for ActiveX repair, simply use this comprehensive register cleaner and your ActiveX errors will be a thing of the past.

Transferring Files Between Windows and UNIX

2008-11-30T03:09:00.000-08:00

Unix FTP can be used to transfer files between PC's and Unix-based file servers
. File transfer protocol (FTP) is the network protocol that is used to transfer the files from the PC to the Unix file server over TCP. The Unix file server will need to have an FTP server installed, and the PC will need to have an FTP client installed. The standard port for FTP communication is port 21. IETF RFC 959 outlines the specifications for FTP.

Most FTP clients use an asynchronous method of communication, also referred to as non-blocking FTP. With this method, the FTP Client uses an asynchronous interface to the Windows sockets TCP/IP driver providing the fastest file transfer data rate possible while using a minimal amount of system resources.

Using FTP, Files can be uploaded and downloaded in either ASCII or binary format. Binary files are files where bytes in the file can be any 256 bit pattern. Examples of binary files include zip files, executables, images, and sound files. ASCII files are text-based binary files that can only use the 128 ASCII codes. Each ASCII character has a corresponding hex value and binary value. For example, the hex value for the letter "A" is 61, and the binary equivalent is 0110 0001.

The FTP server on the Unix server can be configured to require usernames and passwords, or to allow anonymous connections. With anonymous access configured, any and all users are able to upload files to and download files from all directories that are configured for public read and write permissions. On Unix servers, the File Manager can be used to set permissions on files and folders so that anonymous users cannot access them. Alternatively, user accounts can be created on the FTP server, assigned a username and password and access permissions applied at the user level.

Secure sockets layer (SSL) can be used for an added layer of security. With standard FTP, data that is transferred between the PC and the Unix server is not encrypted. Using FTP with SSL (FTPS) ensures that the data being transferred is protected from eavesdropping, tampering, or message forgery by encrypting the data before transferring it. IETF RFC 4217: "Securing FTP with TLS" outlines the specifications for FTP with SSL/TLS security. According to security standard for FTP, by default SSL encryption is only enabled on the command channel. This means that usernames, passwords and file locations are protected, but the transferred files remain vulnerable. To implicitly protect files that are uploaded and downloaded, the data channel also needs to be encrypted by enabling this configuration option in the FTP client.

Advanced FTP clients also provide additional productivity-enhancing features such as an intuitive GUI, the ability to save and transfer entire lists of files, and the ability to save a list of recently transferred files. A Windows GUI allows users to connect to the Unix server and manipulate the necessary files without having to become accustomed to the Unix interface. Many users transfer a specified list of files on a regular basis, or have the need to upload and download the same file multiple times. In this case, recent and custom file transfer lists can save users a lot of time.

With the popularity of Unix servers on the rise, Unix compatible FTP solutions are becoming increasingly commonplace and continue to expand their feature base.

10 Reasons to Use Apple Computers

2008-11-30T03:08:00.000-08:00

Apple computers are known as the sexiest computers in the market. But Apple’s Mac computers have more to it than looks. In fact, a lot of people even say that its operating system and applications is better than any other computer they know of. So what makes Mac computers stand out from the pack? Well, below are some of the reasons:

Less software installed

Is having less software on your computer really better? Some people won’t agree but every IT expert will tell you that the less software you have the better. Why? It is because you will have more disk space, lesser problems, and faster processing. Apple enables you to install only a few necessary programs with a variety of applications.

The Mac OS X is more lenient

The Windows XP and the Windows Vista makes it difficult for you to install a duplicate copy on another computer. The installation is easy and hassle-free; you don’t need to worry about staying activated because you will be. The Mac OS doesn’t require you to register before you decide to upgrade and they won’t look into your computer to look for duplicate copies.

Mac pushes the limits

Apple don’t only push the limits of technology in terms of hardware, it also does this in terms of design and functionality. Mac is best known for its fruit-colored computers while other companies were pushing for the serious look of using black and white. It has also shown in versatility when it dropped the SCSI support and drop serial in favor of the FireWire and the USB support.

Mac can run on Windows

Mac computers can run on Windows but PCs cannot legally or legitimately run on Mac OS X. The question is, if you’re using a Mac, why would you want to run on other PC software? It is not really a question of why though because sometimes it simply becomes inevitable. For example, if Photoshop stopped working after you used Leopard, you will need to install the PC version on your Mac. It’s nice to have the option if you really have to.

Mac has a higher “second hand value”

If you’re trying to sell used computers, it is difficult. You will have to lower it as much as you could and you might not even make decent money for all your efforts. The PC market is crowded and trying to unload used goods into it is bound to be challenging. The story is quite different for a Mac computer. People will still pay for this stuff. And they will be happy to pay a higher price too.

Mac computers are hard to get rid of

If you need to replace your PC every 2 years to keep up with the times, you have no such problem with a Mac computer. Their applications are so far ahead of its time and are usually so useful that you can use it conveniently for years. You will definitely have a hard time getting rid of your trusty old Mac even if you want to.

Buying Tips: How to Buy A Used Computer

2008-11-30T03:07:00.000-08:00

Today, many people consider having a computer as a must. Whether it may be for school, work, research, or simply for recreational purposes, a computer is definitely something that most people cannot live without.

But not all people are ready to invest in such a huge sum to get a computer. Fortunately, anyone can now buy used computers nowadays. Used computers are of course less expensive than new ones, but can still perform and function well. Although most people often associate used computers with bad quality, there are used computers that function as well as new ones, provided you know what to look for in one.

Assess Your Needs

Just as with any purchase decision, assess your needs before buying a used computer. Is mobility important to you? Will you need a personal desktop computer or a laptop? Will you use it to simply create documents and files, or will you use it for Internet or gaming? Also identify if you’ll need a large range of memory or not. By determining your needs beforehand, you can better find a used computer that suits you and your budget.

Do Your Homework

It pays to do research beforehand. If you walk in straight to a used computer store, you might get overwhelmed by the number of choices presented before you. You’ll end up leaving the place in a more confused state. Also, it might be annoying to have a salesperson constantly following you to bombard you with a computer’s specifications. The best way to avoid this is to do your homework beforehand. Do some research online so you can have an idea on what computer specs you will be buying. This way, when you leave your house, you will have a more definite picture on what you’ll be buying, and will more likely end up buying what you need.

Go for Brick and Mortar Shops

Although you can do your research online, it’s sometimes best to buy the actual product on land based shops. This way, you can actually get to test and try out the product, which is very important since after all, it is a used computer. You can thoroughly inspect it and judge whether or not it justifies the price. Also, this eliminates extra costs such as shipping and handling costs, which usually come with online stores. But buying from online stores have its advantages as well so be careful in weighting the pros and cons of this option.

Online Stores with Warranty

If you choose to buy used computers online, then at least choose a store that gives you a warranty and a money back guarantee. Because you cannot inspect and try the computer out for yourself, the best insurance you can get for yourself when buying used computers online is through a warranty or money back guarantee. You will also have higher chances of locating your dream computer online, since there are many resources available in the Internet.

High Powered Gaming Moves to Notebook PCs

2008-11-30T03:06:00.000-08:00

PC games that are resource intensive have been restricted to desktop systems until recently as portable devices were still not powerful enough to allow the games to run smoothly. Usually, these are 3D games that require a lot of CPU and graphics processing power. Even high-end laptop have been unable to meet such demands the same way as their desktop counterparts. Hence, consumers have found it difficult to bring their favorite 3D games along when on the move.

However, with the release of Intel's Core i7 processors, all that is about to change. The Intel Core i7 is a whole new generation of processors that runs on the X58 chipset.

The Core i7 platform offers support for triple-channel DDR3 memory. The way memory works on the new systems is also different. Traditionally, memory controller have been located outside the CPU. For improved performance, each core of the i7 processor now has an in-built memory controller. This allows communication of the CPU and the memory to operate at maximum efficiency.

When considering any computer system, the CPU, memory and graphics are the most important components for many gamers. For 3D games to run at optimal level, the system has to be equipped with adequate graphics processing power as well.

The first few generations of computer systems used the CPU to process graphics. After a few short years, the evolution of applications demanded more processing power. As a result, motherboard manufacturers started to offload all graphics processing activities to a dedicated piece of hardware - the graphics card. This allows graphics and video to be processed in a more specialized manner, thus greatly enhancing video capabilities.

With the surge of 3D and video applications, the demand for even more graphics processing power is increasing. To scale processing power, there are only two ways to go. The first option is to increase the speed values of the processor. For example, a 1.5 MHz CPU can be upgraded to a 2.0 MHz CPU. The second option is have more CPUs, sharing the workload. That is why we have dual core and quad core CPUs.

For the video card, the scaling process is similar. NVIDIA came up with a way to offer multi-GPU (Graphics Processing Unit) capabilities. They call this technology SLI. Unfortunately, not all motherboards offer SLI support automatically. Only higher-end models offer support for SLI.

The Toshiba Qosmio X305 notebook, aimed at gamers who require high-end graphics resources, comes with support for Triple-SLI. Triple-SLI means that there are three GPUs configured in the notebook. This is the first notebook that uses this configuration.

With such powerful configurations, gamers no longer have to worry about not being able to bring their favorite 3D games along with them while they travel.

Check Disk Errors and How to Prevent Them

2008-11-30T03:05:00.000-08:00

There are two things going on in your computer at all times: The file system and your hard drive. When your computer is on, the file system is hard at work processing and making things happen. The hard drive actively records and then stores this information. Think of it like this: the file system is like a courtroom. All sorts of things are happening: testimonies being made and evidence presented. The hard drive is like the court reporter, recording all the information. As soon as the courtroom shuts down for the day, its essential to have an accurate record of that day’s proceedings. This exchange can go awry for a number of reasons. For example, if your computer freezes, and you are forced to shut down, the hard drive may not finish recording a piece of information. Or the hard drive itself can be damaged internally, by something simple like someone bumping into it. (Your hard drive, or hard disk, records information almost like a record or CD and can get scratched.) Luckily, commands like Check Disk, or Chkdsk exist for DOS, OS/2 and Windows operating systems. Chkdsk is used to find and fix errors on the hard drive. Your computer will prompt it to run when there is an error or errors. Using the example above, if your computer freezes and you are forced to restart, Chkdsk will run when you start back up. It will scan your hard drive, and fix any problems.

Unfortunately, Chkdsk can sometimes become corrupted or encounter problems in the registry. Chkdsk errors usually indicate a damaged registry.

The registry is a directory that stores fundamental settings and options for your Windows operating system—it is literally the most important set of data on your computer. It keeps information about your hardware (like your mouse, keyboard, or monitor), software (Windows 2000 or Microsoft Word for example), and user settings and preferences. The registry is constantly being added to and/or updated. If you install a new program, view a web page for the first time, or download something in your email, new information may be added or overwritten in the registry. Unfortunately, over time, this directory can become crowded, disorganized, and/or information may have been replaced. Registry repair is essential to ensure error-free operation of your computer. RegCure is the most advanced Windows registry cleaner on the market and uses advanced technology to scan your registry for missing, obsolete, and corrupt entries. At RegistryRepairProgram.com, you can download a free scan for your computer. If you elect to use RegCure, your registry will be repaired eliminating problems like Check disk errors. Most of us would rather not wait until our computer crashes (potentially losing valuable information) before realizing their PC has errors. Using a registry cleaner can fix any issues before they become a major challenge. Additionally, if your registry is tip-top shape, it will eliminate any Check disk errors.

History of laptops

2008-11-30T02:57:00.000-08:00

The concept of laptops developed when more and more people were clamoring for a portable computer they can work with while traveling and carry it to different locations. The laptops that were initially introduced were somewhat crude and lacked the sophistication of the laptops as we know and see them today. They were very bulky, had very small displays, without hard drives and everything ran from the RAM or floppy disks.

In 1981 the Osborne Computer Company released the first portable computer and called it Osborne 1. This laptop computer, when not in use and closed up, resembled a locked up sewing machine. It was powered by an electrical connection with an optional laptop battery backup. It had two 5 ¼" floppy drives (mounted to the right and left of the display), and included a modem port. The biggest drawback was the display was only 5-inches wide and could show only a limited 52 characters per line.

Then in 1983, Gavilan introduced the Gavilan Mobile Computer. It was peculiarly built and the screen folded over the keyboard when closed. It weighed 9 pounds, and could run on nickel-cadmium batteries for close to 9 hours.

Three years later in 1986,Radio Shack released the TRS – 80 Model 200 This model was more compact, had a much larger display and more effective laptop battery power, and included built-in software. People used this model for creating simple documents and considered it to be pretty high tech at that time.

A year later in 1987, IBM released its version of a laptop computer calling it the 5155 Portable Personal Computer. It had two double-sided 5 ¼" drives and 640K RAM. The 5155 however did not support graphics and was used for the limited processing of text-based information only.

During 1988, Compaq introduced the SLT/286 Laptop which had overcome the graphics barrier. This model however weighed a hefty 14 pounds, had a 1.44 floppy drive and ‘286’ processor. NEC joined the fray with the NEC UltraLite, which weighed just 4.4 pounds and had overall dimensions of 11.75" (W) X 1.4" (H) X 8.3" (D).

Macintosh entered the laptop scenario in 1989 with their Portable that weighed around16 pounds and had a 9.8-inch 640 x 400 active matrix screen. Its redeeming feature was an operation time of close to 10 hours on a lead-acid battery. These early laptops from Macintosh later evolved into the PowerBook line and now the MacBook line.

It was only in the 1990s we saw the faster, sleeker machines with more storage, more ports and connectors, improved displays, and weighing much less and comfortable enough to carry around. The Apple Macintosh PowerBook line and the IBM ThinkPads became major competitors in the laptop market.

Companies now create new laptops with faster processors and more features packed in smaller packages and the laptopshave really come a long long way from the 1981 Osborne model. Since the 90's the technology has helped to vastly improve the performance of laptop computers. Longer lasting laptop battery as well as huge hard drives now makes the Laptop a serious challenger to oust the desktop computers from the marketThe summer of 1995 was a watershed year in the history of laptop computers. In August of that year Microsoft introduced Windows 95. It was the first time that Microsoft had placed much of the power management control in the operating system. This move held a great deal in simplifying and stabilizing certain key aspects of notebookdesign. Windows 95 also brought in the importance of the CD-Rom drive in mobile computing, and initiated the shift to the Intel Pentium processor as the base platform for notebooks.

Video Analytics Solutions for Commercial Enterprises

2008-11-30T02:55:00.000-08:00

Office complexes, manufacturers, warehouses, service firms, corporate enterprises and more can all benefit from video analytics. Intelligent video software, when used in conjunction with video surveillance, can provide a variety of functions to improve the efficiency of basic operations, increase safety and security and much more.

Efficiency and Effectiveness

Video analytics is a growing technology which greatly increases the efficiency and effectiveness of video surveillance systems. Powerful software is able to analyze video pixel by pixel all in real time for increased and quickened information flows. Beyond in depth analysis, video analytics can also be used in transferring information to those who need it when they need it.

Built upon Internet networks, video analytics is a powerful part of a remote access security network. Managers, security personnel and employees can all access the system from any computer with an Internet connection. This allows for remote monitoring and information gathering to occur at any time, day or night, regardless of where users may be.

For protection of this online surveillance system, high level encryption is utilized. This is then combined with a multi-level password system which controls who is able to do what with the software, and keeps unauthorized personnel out of the system all together.

Improving Security

Security is important for any security operation. The intelligent software can keep a close tab on restricted areas, for example, and automatically notify managers, security and other required personnel should unauthorized persons enter these areas. Video motion detection and other alarm triggers can also be used to activate alarms during off-hours, so your software is providing 24/7 protection.

Many video analytics software programs can also utilize object recognition capabilities. Objects are programmed into the software, then should anything happen to the object, such as it becoming damaged or moved, the software can recognize this event and send out immediate alerts so that appropriate action can be taken at once. This is especially helpful in manufacturing plants and warehouses which might have important and high risk objects which need extra protection.

Video analytics software can even be programmed to differentiate between normal and suspicious behavior. Should anyone be seen acting in a suspicious manner, the software can then notify required personnel so they can keep tabs on the situation and to keep the situation from becoming a problem.

Employee Management

Employee management is another area in which video analytics can be very helpful. This includes ensuring that employees are following proper procedures and standard operating practices. The software can also analyze employee patterns so that management can keep tabs on exactly what employees are doing and when to improve overall efficiency, whatever your commercial enterprise may be.

Improving Overall Efficiency and Effectiveness

Whatever your operation, video analytics can help you in increasing your overall efficiency and effectiveness. Keeping detailed records and powerful analysis of daily operations can help managers to identify areas of inefficiency, and develop new methods to better complete the company's mission.

The best part of all this is that the software is able to perform all of these functions automatically. Your commercial enterprise can save money in needing constant and full monitoring of video surveillance systems, as the software can identify many problems on its own. It also serves as a powerful back up system, picking up on things that might be missed by employees on their own.

Work can also be done off-site, as needed, saving in travel times and costs. This is another great benefit which commercial enterprises receive when using video analytics technology. Remote access is a powerful tool and one of the many solutions that video analytics technology provides.

The Next Generation of Portable Media Players

2008-11-30T02:54:00.000-08:00

Portable media players are becoming more and more popular. With the widespread use of WiFi (wireless Internet access) penetrating our daily lives in cafes, schools, libraries, airports, and other public spots, more and more people are turning to portable gadgets.

Portable gadgets can be used for play or work. These gadgets may include portable media players, laptops, netbooks, or the UMPC (Ultra Mobile PC). The type of gadget that a consumer decides to buy depends very much on his or her own personal needs and wants. For example, if an individual wants to use a portable gadget for work, a laptop may be the best option. That's because the laptop is able to house more powerful hardware, and more applications can be run from the system. However, the drawback is that most laptops are still bulky compared to other portable gadgets.

In contrast, modern entertainment gadgets that are portable are lighter, smaller, and come in more popular designs. The Archos 5 Internet media tablet is such an example.

The Archos media tablet has its own built-in CPU. However, as this gadget is meant mainly for entertainment purposes, the CPU is often left out of the limelight. Most consumers are mainly concerned about whether the graphics will run smoothly, and how many movies they can store on the media player.

You can use the Archos media player to watch TV content, stream movies over the Internet, or play your own movies. This device supports many media formats. Formats include MPEG, WMV, H.264, AVI, and DivX. There is no QWERTY keyboard available. All the commands are issued using touch screen. The only off screen operations are the power and the volume control.

This gadget comes in 3 versions - 60GB, 120GB, and 250GB. The smallest version weighs only .55 pounds, while the other two versions weigh .66 pounds. That means you can easily bring the device wherever you go without hassle. The amount of disk space required depends on how much content you wish to store in the gadget. Given the advanced compression technology available today, each high quality movie will usually require no more than 1GB of disk space.

There are many ways that an individual can store content in a media player. Content can be easily downloaded over the Internet. Or special software can be used to convert VCD or DVD movies into digital formats. The media player can also be connected to the television set for recording of programs.

If you grow tired of existing content, you can also connect to the Internet to perform some simple operations like web browsing or checking email. While connected to the Internet, you can download more content such as movies, Anime episodes, or simply stream content without downloading.

Obviously, a portable media player is a great traveling companion. You can use the gadget to provide you with some great entertainment while waiting for a flight, or while you are in the hotel. This useful gadget retails for less than $500. For all the functions that it performs, it's definitely worth considering.

High Definition Video

2008-11-30T02:53:00.000-08:00

High Definition television normally refers to any video system of higher resolution than the standard definition. The original high definition specifications date back to the early 1980s, when Japan first experimented with a 1025 line television standard. The signals for high definition require a high definition television or a computer monitor in order to be watched or viewed. High definition will normally have an aspect ratio of 16:9. The aspect ratio of the regular wide screen film that is shot today is normally 1:85:1 or 2:40:1. The standard type of television has a 4:3 aspect ratio. When high definition first unveiled the H3 to the market, it staged none of the over the top glitz or glamor many expected. Held at a tiny theater in Tokyo, the event barely even resembled a minor product launch. High Definition cameras also offers a memory stick setup system that memorizes various parameters and enables instant recall. Once you set up for the first time, it will remember the settings then go right back to the previous parameters at the touch of a button.

High Definition camcorders came out later on, which the ability to put them on your computer or even take your camera card to a local store and have the photos printed out on professional paper. Over the years, camcorders have evolved in so many ways that it is not even funny. These days, high definition video camcorders are dominating the market. They are relatively new and quickly catching on, giving you so much you can do with your camera. Unlike the past, camcorders are now capable of capturing full videos as well, proving that they are indeed capable of capturing any memory you can possibly imagine. On the other hand, if you take a lot of pictures and enjoy making videos, buying a camera may be the best option for you. Even though they cost a lot of money, these cameras are ideal for anyone who is seeking the absolute best in technology. These cameras are nothing like cameras of the past, as they can do so much more with a lot better quality.

Cameras that offer high definition are simply the best you can buy. They are obviously more expensive than digital camcorders, with some models reaching upwards towards 90,000 and above! These types of cameras are normally for professionals, as the average working man would never be able to afford such an expensive type of high definition camera. The average high definition video will run 800 and up. high definition camcorders offer you the chance to shoot high definition pictures and videos, and send them to friends or family. You can also save your shoots to disk or memory card, then take them with you everywhere you go.

The high definition is designed for a variety of remote acquisition applications, especially in television production for recording programs and for use as a weather or even traffic camera. The Pan Tilt Zoom can display images onto a large screen in auditoriums, teaching hospitals, sporting events, trade shows, and even concerts. This unit is also ideal for distance learning applications in which clear high definition images need to be projected onto electronic white boards during a presentation or other function.

Keep in mind that you need a powerful computer with a lot of memory to deal with the extra data and compression. Pinnacle for example, recommends a minimum 512 MB of RAM and a graphics card with 128 MB of RAM for standard resolution video. You can find plenty of software available that supports editing high definition videos. For example, the latest versions of Pinnacle Studio and Media Studio 8 can import and edit files in high definition format.

If you only plan to use your camera for a few days or just a short period of time, then renting may be your best option. Producers and professional photographers looking to take things to the next level, may choose rent a high definition video to test the waters before making the purchase. If you have never experienced high definition before, renting may be the best idea before you sink a ton of money into buying one of your very own.

Sony PlayStation 3 (PS3) Console Hardware Review

2008-11-30T02:52:00.000-08:00

Any gamer looking to purchase a video game console has to consider several issues. These issues ultimately affect the buying decision, and depending on individual preferences, some will certainly outweigh others. So it's important to know what your own preferences are before setting out to buy a piece of video game hardware. After all, video game consoles can be rather costly, costing three hundred dollars and up a piece. Therefore, it's always a wise thing to do a little bit of home and read some reviews before making any decisions - which is probably why you are here, as this is going to be a review on Sony's PlayStation 3 (PS3).

Now when doing your own research on which video game console is best suited for you, you may want to start with performance. There are performance in various category such as graphics and CPU processing speed. But let's just start with looking at CPU performance. Sony Playstation 3 (PS3) boasts of a unique cell processor. How a cell processor works is that the processor has several different cells, all capable of processing information at the same time. This make it the most powerful CPU that a video game console has on the market. Some reviewers have claimed that this most of the CPU resources have not been utilized, and this is true to a certain extent. I would, however, argue that for Sony has been developed with the future in mind. With so much raw power, it is exciting to imagine what the console can achieve in a few short years. The executives in Sony has in fact, adopted a more far-sighted approach and built in a very powerful processor right from the onset. Therefore, all claims that the PlayStation 3 (PS3) arrived late in the marketplace is simply unfounded. Keep your eyes on this video console and it'll soon lead the pack in a few years time.

Another main area of concern for video game consoles, is graphics. Graphics have always been one of the most talked about topic among gamers. To be fair, gamers should only compare graphics with games that are exclusive to each video console. That's because multi platform games may not be designed to fully utilize the potential in a video console, as the focus is on compatibility instead of performance. Everyone seems to be comparing graphics performance between the XBox and Sony Playstation 3 (PS3). From our own tests, Playstation displays 3D renderings with far more sharpness. And that can only be achieved with high end technology. The end result is that you get much more realistic environments. You don't have to take our word for it, simply make the observations yourself.

And finally, all gamers should consider the list of exclusive games before buying any video console. This factor, by and large, depends very heavily on the individual personal preference. We can get away with graphics or CPU performance issues. For some, as long as the games are playable on the console, who cares. But if the gamer falls in love with a game, and must absolutely get his hands on it, then he is out of luck if the console he owns doesn't support the game. So remember to check out some games, and see which console has your favorites on them.

To sum it all up, the PlayStation 3 (PS3) is a high end gaming machine. No doubt it has a slightly heftier price tag compared to the Xbox, but if you're a true hardcore gaming fan, you probably wouldn't mind the 50 to 100 dollars difference. That being said, I'm sure the executives at Sony firmly believes that true gamers know an excellent video console when they see one. And thus the decision to incorporate highly advanced hardware into the console, way ahead of its competition, even if it means bringing the cost higher. And I'm sure, in time to come, all true gamers will come to recognize that, and share the vision and excitement with the Sony executives.

Learning More About Internet Phone Adapters

2008-11-30T02:51:00.000-08:00

Before we dive into internet phone adapters, you have to first understand more about how VoIP phone calls are made. When we make a phone call using a traditional land line, the voice signal that we send over the phone network is an analog signal. This signal is transmitted over the network and someone on the other end hears the voice.

The problem with such phone calls is that they lead to huge bills, especially when the calls are made to faraway countries. Before the Internet was invented, there was no other way to make international phone calls. So consumers have no choice but to pay hefty phone bills for their usage. The longer the duration of the calls, the bigger the bills.

Fortunately, the Internet offers an alternative way to make overseas phone calls. Data is transferred over the internet in the digital format, not in the analog format. So special hardware or software is required to convert the analog voice signal to the digital format, so that it can be transmitted over the internet. Once the data is converted into digital audio format, it can easily be transmitted using the Internet protocol (IP). This technology is called VoIP (voice over IP) technology.

For a VoIP call to work, a broadband internet connection is needed. If a computer is available, a VoIP can be made when special software has been installed in the system. Of course, a headset with a mic is necessary for delivering and receiving voice data.

However, not everyone likes the idea of having to use a computer just to make a simple phone call. An individual can make a VoIP call without using a computer by using an IP phone. This is a special phone that allows the voice to be converted to the digital format.

Still, some people are not satisfied. They argue that since they already have phones at home, why should they invest in additional hardware? So VoIP equipment engineers came up with internet phone adapters. You can connect an ordinary phone to an internet phone adapter, and make a VoIP phone call. Of course, the internet phone adapter must be connected to a modem, which in turn is connected to the internet.

There are many different types of internet phone adapters. The most common adapters have RJ45 sockets. Most home phones are connected to the RJ45 sockets. You can also use a USB phone adapter to connect to a computer. If you have more than 1 internet phone, you may wish to consider buying a 2/3/4 way internet phone adapter.

Internet phone adapters are widely available. You should be able to find them from local computer stores, or from online computer equipment retailers. When in doubt, always consult your service provider on the right adapter to buy.

Is PDA Tracking the Solution to Keeping Mobile Workers Safe?

2008-11-30T02:45:00.001-08:00

There are many workers in the UK that are now classified as mobile or lone workers since much of their day to day work involves them working outside of the centralised office environment. It may be that they are a night time security guard or that they work for the social services and are frequently out of the office on home visits. Whatever their job title mobile workers often find themselves in unusual situations, but like office based workers their employers must ensure that they are protected and kept safe whilst on the road.

It is a general legal duty of employers under Section 2 of the Health and Safety at Work Act to maintain safe working arrangements for all their employees whether mobile or office based. In order to comply with this rule Section 3 of the Management of Health and Safety at Work Regulations requires that employers must also carry out full risk assessments of the hazards to which their employees are exposed. For mobile workers these risks or hazards could include violent encounters from the general public, sudden illness or road traffic accidents.

As a result of this modern businesses now have strict rules and regulations for mobile workers and have detailed risk assessment documents that identify the possible risks and outline the measures they have put in place to help prevent these risks from occurring. In accordance with risk assessment laws, employers should consider in their assessment whether or not a single person can do the work safely and what arrangements are required to ensure the lone worker is at no more risk than employees working together.

For many employers and business owners these laws alongside the Duty of Care Legislation, which was introduced in 1991, have led to an increased awareness about their workers safety. Employers have had to respond to this legislation by introducing new methods of achieving these levels of safely.

As these laws and regulations have developed so to have the technologies and equipment used to help keep lone workers safe. Personal Digital Assistants are one such technology and have quickly become the mobile device of choice for many organisations. PDA’s enable business owners to get critical information to their mobile employees quickly and in real time, something that has proven to be indispensable in the modern business world.

A PDA device also enables business owners and managers to answer some of the many questions they must take into consideration when evaluating mobile worker risk. For example, when considering remote working it may be necessary to establish guidelines as to when the lone worker should check in with their managers or supervisors or track their movements in order to ensure their safety.

With PDA’s being readily available and carried by many mobile workers, innovative software solutions are now being utilised in order to keep track of these workers whereabouts at all times. As long as the PDA is switched on, tracking systems are able to pinpoint their exact location via a mapping system. A discreet panic button can be added should any member of your workforce need it. These panic buttons have the facility to be mounted in different locations for instance in a vehicle in order top make them as versatile as possible.

PDA tracking systems have a number of benefits making it a wise choice when thinking about safeguarding your mobile workers. The tracking software is able to be used with any Windows mobile device such as a PDA. Combine this with its covert possibilities, optional lone worker application, and access to Internet mapping amongst others, makes it a powerful tool for any business with mobile workers.

Even if your company does not have its own PDA’s, the tracking system provider can supply these. In short, the benefits of tracking systems and PDA tracking software are so great and diverse that it is an effective method of tracking and safeguarding workers against harm or unforeseen circumstances.
