Cheap Computer Repair Does Not Mean Bad Computer Repair
When people are looking for cheap computer repair they need to consider a few important things. The first is you get what you pay for. This does not mean you can't find a great cheap computer repair company. I say this because many times the cheaper person is not insured and does not offer a guarantee. A perfect example of this is just last week. I had a customer who gave me call and said they needed their computer repaired. They took it to a guy they found on craigslist and yes he was cheap but the guy also had their computer for a full week and the issue was not resolved. He did say he had 20 years of computer repair experience but they still got burned.
When choosing a cheap computer repair company always ask how long the company has been in business. If they have only been open a few months consider going some were else. 85% of all companies do not make it to the one year mark.
Another great question to ask is if they have any computer certifications. At the very least they should have an A+ certification. This is the most basic cert in the industry.
When you find someone who offers a great price ask about any guarantees and if the price includes the full cost of the repair. Some places charge by the hour. I never go this route for computer repair. The tech might quote you $25 dollars an hour and say it will only take 2 hours to repair. Then 5 hours later you paid double what you wanted. The guarantee matters as well. Being in the business I can tell you that yes 90% of the time I am able to remove the virus the first time. However you really do not fully know if the virus is gone until a few days later. If you missed one trace the thing can reactivate and that is were the guarantee comes into place.
Having you computer repaired online for software issues and viruses is the cheapest way to go hands down. Be sure to find one that has a "No Fix No Fee" policy and that charges by the service and not the hour. This way you know ahead of time if the issue is not fixed you do not pay and you know exactly how much the repair will cost ahead of time. Be sure and ask what kinds of guarantees the company offers as well. If your issue comes back you want to know it will be taken care of with out any further costs to you.
If your in the market for computer repair consider us at Online Computer Repair. We do not charge if we can't fix the issue and have some of the best prices around. You may also want to visit our Vista Repair site for more computer repair tips.

Computer Components for Idiots
There are many fancy add-ons for computers, but the basic components of the computer are simple and universal. If 1 of these main components is missing, it’s not a computer.
The 4 essentials of every computer system are: a motherboard, a Central Processing Unit (CPU), memory, and a hard drive. These components are installed in a case to which are attached a monitor, a keyboard and a mouse. That’s your basic computer.
Mother WHAT?
The motherboard ("mobo" for short) is the foundation. Everything attaches to the mobo -- the CPU, memory, hard drive, monitor, mouse, keyboard, add-on cards, even additional peripherals like printers, scanners, and speakers. The motherboard is like the nervous system and skeleton of the human body -- it provides support for the internal components and also passes information between the computer parts.
CPU
If the motherboard is the nervous system, then the CPU is the brain. Most of the mathematical manipulations that make computers operate are done by the CPU. Other components may also have their own processors, but their results still have to be passed through the CPU.
The speed of the computer is usually measured by the speed of the CPU. Even though other factors also affect overall speed, the CPU rating is generally seen as the single most important measure of performance.
Modern CPUs are usually rated between 2.0 GHz and 3.0 GHz, although each passing month will see increasing performance. This measurement refer to the number of calculations the processor can make in 1 second. The higher the number, the faster (better) the computer.
CPUs generate a lot of heat doing this work, so they need a heat sink and fan to keep them from overheating. Heat is a major enemy of the computer and directly affects its life span.
Computer Memory
RAM (Random Access Memory) is the part of the computer that stores information the computer needs while it is operating. It is Random Access because the computer can get the data in any order, not necessarily the order in which it is stored. Generally speaking, the more RAM the better. 512 to 1024 megabytes is common for memory.
The most common type of RAM these days is DDR-SDRAM, which stands for double-data-rate synchronous dynamic random access memory. We already know what the RAM part means. DDR means that the data is accessed twice as fast as ordinary RAM.
The latest type of RAM is DDR2. It offers even faster access rates and is quickly becoming the standard for computer memory.
Hard Drive
All the data contained in RAM is lost when the computer is turned off, so there has to be a place to store it permanently. This is what the hard disk is for.
It holds the computer’s operating system. An operating system like Windows uses around 4 gigabytes of hard drive space. The extra space is used to install computer programs and to store your personal data.
80 gigabyte hard drives are common, but 400 GB units are available. Furthermore, you can install more than 1 in a computer case for added security and convenience.
Peripherals
All you need to complete the basic computer system is a monitor, keyboard and mouse.
Accessories like a printer or scanner are useful for office work, and gamers will probably want to add speakers and joystick controls.
So there you have it. The basic computer needs just 7 major components. For the best performance, these components must integrate well. The motherboard is the most important component for determining the type and specification of the other parts. Choosing an appropriate mobo for your computer needs is the first step and may require a quick call to your local geek.
Soon YOU will be considered the local geek!

Steps To Maintaining Your Personal Computer
1. Safety First!! - Protect your computer from viruses and spyware.
Many PCs will come with a free trial version of an Anti-Virus Software. However, once this trial expires, what should a basic home user do?
It is very common for people to either choose to go without Anti-Virus, or to pay for a subscription to Norton. However, Norton produces annoying pop-ups and warnings, and also takes up so much of a computer's RAM that it will actually slow down the PC's performance.
I recommend AVG's Anti-virus. It is a free program that provides very sufficient protection for your computer. It can be downloaded at the link below. AVG should be updated and a scan should be performed AT LEAST once a week.
Additionally, you must protect your computer from spyware. According to Microsoft, "Spyware is a general term used to describe software that performs certain behaviors such as advertising, collecting personal information, or changing the configuration of your computer, generally without appropriately obtaining your consent first." It can be very harmful and is commonly overlooked when basic users are protecting their PC.
A very useful program to sweep your system of spyware is Spybot Search & Destroy. It is also a free program and can be downloaded at the link below. It should be updated and a scan should be performed once every couple of weeks.
2. Don't make your hard drive work too hard.
Like any car or home appliance, a computer's hard drive will suffer from "wear and tear." You can usually expect a hard drive to last 4-5 years but that can be greatly increased by giving your hard drive the occasional tune up.
The first step of doing this is running the Windows Disk Cleanup Tool. This is done by clicking Start --> All Programs --> Accessories --> System Tools --> Disk Cleanup. It will scan your computer, and provide you with a list of files you can choose to remove. This will remove any files on your computer that may not be needed and are simply taking up space. Disk Cleanup should be performed approximately once a month for the average user.
Next, you should run the Disk Defragmenter. The hard drive can become fragmented with a greater frequency of new software installations, internet downloads of movies or music, or simple creation of files. Fragmenting of a hard drive occurs because all files are stored in sectors and when a file is opened a needle has to find all parts of that file on the hard drive. When a file is created it won't be one large package, but many small packages that make up the whole. When these packages are stored, they will be placed in the first open area on the hard drive. If a hard drive is fragmented, the packages will not be placed together and will force the drive to work harder to build the file. This can decrease both the lifespan of the drive and the speed of your computer.
Defragmenting simply places all of the files in a position that relieves the stress on a hard drive. It can be done by clicking Start --> All Programs --> Accessories --> System Tools --> Disk Defragmenter. You can then click analyze in Windows XP and it will give you a response on whether or not you should defragment. Windows Vista now allows you to schedule how often you would like to defragment. This should be done AT LEAST quarterly for an average user but might need to be done more often for some.
3. UPDATE!!
Windows allows a user to permit automatic updates, so take advantage of it. This can be done by clicking Start --> All Programs --> Windows Update. It should be set to automatic so that you can be as up to date as possible on the built in security measures that windows has already installed.
It is also a good idea to check on updates for any programs that you have installed. This is not necessarily needed but is recommended to get the most out of your programs. It can usually be done by opening the program and then looking for "Update" in the Help Menu.
4. Do Some Spring Cleaning
All computers have fans that encourage air flow through the tower to ensure that the processor runs at a cooler temperature. Dust and pet hair can clog these vents and overheat your processor. This must be cleaned to prevent a very expensive repair. Every computer technician has a story about a computer that they opened up and everything was caked in dust. Don't let this be you. It may be intimidating to some to open up the computer's case, but it is quite simple.
Go to your local PC shop and purchase a can of compressed air, which will only cost a few dollars. MAKE SURE EVERYTHING IS UNPLUGGED!! Open up your computer's tower. It should only be a couple of screws but if you can't figure it out then you probably shouldn't open it in the first place. Use the compressed air to remove any of the dust on the motherboard, fan and processor. Close everything back up and you are all done.
You can also use the compressed air to clean your keyboard. Use alcohol and a soft cloth to clean your monitor's screen. You can also purchase a CD-ROM Cleaner that will clean your drive. It is basically a felt cd that is put in the drive to clean the optical lens.
Follow these steps and you will greatly increase the performance and longevity of your computer.

Delete Computer History
If you want to maintain your privacy on your very own computer, then you will need to delete your computer history. Your computer maintains a file of everything you do. And no matter what you do, you will not completely erase your footprints of where you have been, whether by accident or on purpose. You need to delete everything.
You have probably been somewhere on the internet you should not have gone. Maybe it started out as an accident, but then curiosity set in, and you kept looking and reading. All of this information is on your computer right now. Just because you erased the cookie, or erased the temporary file, then deleted the internet history file, and even emptied the recycle bin, you still have proof of your viewings on your computer. This is how so many people get caught doing stuff they should not be doing. They assume this stuff is gone, and it is there all the time, even right now.
Don’t worry, though. There are software programs, which can delete computer history for good. This is beneficial in many ways, as it will protect you and your privacy. No need for the wife, girlfriend, boyfriend, or husband to see what you might be looking at. It is really none of their business. But in order to do that, you need to clear that history on your computer completely. It takes more than just a delete of the file and an empty of the recycle bin. Specialized data recovery software programs can recover your data within minutes.
Even if you view images, these can be traced back as well. Everything you have ever done and the proof of you trying to delete the files are all noticeable, and can be found. Do not let this happen to you. Keep your tracks hidden and privacy protected by using history erase software to delete computer history.

ATA vs SATA
Hard Drives: ATA versus SATA
The performance of computer systems has been steadily increasing as faster processors, memory, and video cards are continuously being developed. The one key component that is often neglected when looking at improving the performance of a computer system is the hard drive. Hard drive manufacturers have been constantly evolving the basic hard drive used in modern computer systems for the last 25 years, and the last few years have seen some exciting developments from faster spindle speeds, larger caches, better reliability, and increased data transmission speeds.
The drive type used most in consumer grade computers is the hearty ATA type drive (commonly called an IDE drive). The ATA standard dates back to 1986 and is based on a 16-bit parallel interface has undergone many evolutions since its introduction to increase the speed and size of the drives that it can support. The latest standard is ATA-7 (first introduced in 2001 by the T13 Technical Committee (the group responsible for the ATA standard)) which supports data transfer rates up to 133MB/sec. This is expected to be the last update for the parallel ATA standard.
As long ago as 2000 it was seen that the parallel ATA standard was maxing out its limitations as to what it could handle. With data rates hitting the 133MB/sec mark on a parallel cable, you are inviting all sorts of problems because of signal timing, EMI (electromagnetic interference) and other data integrity issues; thus industry leaders got together and came up with a new standard known as Serial ATA (SATA). SATA has only been around a few years, but is destined to become “the standard” due to several benefits to be addressed in this Tech Tip.
The two technologies that we will be looking at are: ATA (Advanced Technology Attachment) – a 16-bit parallel interface used for controlling computer drives. Introduced in 1986, it has undergone many evolutions in the last 18+ years, with the latest version being called ATA-7. Wherever an item is referred to as being an ATA device, it is commonly a Parallel ATA device. ATA devices are also commonly called IDE, EIDE, Ultra-ATA, Ultra-DMA, ATAPI, PATA, etc. (each of these acronyms actually do refer to very specific items, but are commonly interchanged) SATA (Serial Advanced Technology Attachment) – a 1-bit serial evolution of the Parallel ATA physical storage interface.
Basic Features & Connections
SATA drives are easy to distinguish from their ATA cousins by the different data and power connections found on the back of the drives. A side-by-side comparison of the two interfaces can be seen in this PDF from Maxtor, and the following covers many of the differences…
Standard ATA drives, such as this 200GB Western Digital model, have somewhat bulky, two inch wide ribbon cable with 40-pin data connections and receive the 5V necessary to power them from the familiar 4-pin connection. The basic data cables for these drives have looked the same for years. A change was made with the introduction of the ATA-5 standard to better improve the signal quality by making an 80 wire cable used on the 40-pin connector (these are commonly called 40-pin/80-wire cables). To improve airflow within the computer system some manufacturers resorted to literally folding over the ribbon cable and taping it into that position. Another recent physical change also came with the advent of rounded cables. The performance of the rounded cables is equal to that of the flat ribbon, but many prefer the improved system air flow afforded, ease of wire management, and cooler appearance that come with them.
SATA drives, such as this 120GB Western Digital model, have a half inch wide, 7 “blade and beam” data connection, which results in a much thinner and easier to manage data cable. These cables take the convenience of the ATA rounded cables to the next level by being even narrower, more flexible and capable of being longer without fear of data loss. SATA cables have a maximum length of 1 meter (39.37 inches), which is much greater than the recommended 18 inch cable for ATA drives. The reduced footprint of SATA data connections frees up space on motherboards, potentially allowing for more convenient layouts and room for more onboard features!
A 15-pin power connection delivers the 250mV of necessary power to SATA drives. 15-pins for a SATA device sounds like it would require a much larger power cable than a 4-pin ATA device, but in reality the two power connectors are just about the same height. For the time being, many SATA drives are also coming with a legacy 4-pin power connector for convenience.
Many modern motherboards, such as this Chaintech motherboard, come with SATA drive connections onboard (many also including the ATA connectors as well for legacy drive compatibility), and new power supplies, such as this Ultra X-Connect, generally feature a few of the necessary 15-pin power connections, making it easy to use these drives on new systems. Older systems can easily be upgraded to support SATA drives by use of adapters, such as this PCI slot SATA controller and this 4-pin to 15-pin SATA power adapter.
Optical drives are also becoming more readily available with SATA connections. Drives such as the Plextor PX-712SA take advantage of the new interface, although the performance will not be any greater than a comparable optical drive with an ATA connection.
Performance
In addition to being more convenient to install and drawing less power, SATA drives have performance benefits that really set them apart from ATA drives.
The most interesting performance feature of SATA is the maximum bandwidth possible. As we have noted, the evolution of ATA drives has seen the data transfer rate reach its maximum at 133 MB/second, where the current SATA standard provides data transfers of up to 150 MB/second. The overall performance increase of SATA over ATA can currently be expected to be up to 5% (according to Seagate), but improvements in SATA technology will surely improve on that.
The future of SATA holds great things for those wanting even more speed, as drives with 300 MB/second transfer rates (SATA II) will be readily available in 2005, and by 2008 speeds of up to 600 MB/second can be expected. Those speeds are incredible, and are hard to imagine at this point.
Another performance benefit found on SATA drives is their built-in hot-swap capabilities. SATA drives can be brought on and offline without shutting down the computer system, providing a serious benefit to those who can’t afford downtime, or who want to move drives in and out of operation quickly. The higher number of wires in the power connection is partially explained by this, as six of the fifteen wires are dedicated to allowing the hot-swap feature.
Price
Comparing ATA drives to SATA drives can be tricky given all of the variables, but in general it is the case that SATA drives will still cost just a bit more than a comparable ATA drive. The gap is closing rapidly though, and as SATA drives gain in popularity and availability a distinct shift in prices can be expected. Considering the benefits of SATA over ATA, the potential difference of a few dollars can easily be justified when considering an upgrade. Computer Geeks currently has a limited selection of SATA drives, but several technical sites, such as The Tech Zone and The Tech Lounge, offer real time price guides to see how comparable drives stack up.
Final Words
The current SATA standard provides significant benefits over ATA in terms of convenience, power consumption and, most importantly, performance. The main thing ATA has going for it right now is history, as it has been the standard for so long that it will not likely disappear any time soon. The future of SATA will be even more interesting as speed increases will help hard drive development keep pace with other key system components.

6 Benefits Of Work At Home Computer Jobs
As the internet continues to evolve, more and more people are turning to work at home computer jobs for obvious reasons. Having a work from home job gives you benefits that you will find with no other profession available. While the list of benefits could go on forever, here are 6 benefits of work at home computer jobs.
1. You choose your career:
When you have a work at home computer job, you have the ability to choose what you want to get into. Certainly you can do this with a 9 to 5 job, but there are not always open positions. With the internet, you can create your own business or join a company that is already having success online.
2. You are the boss:
Finally no more listening to duties and doing projects you are not interested in. You can work when you want, start any kinds of projects that you want, and take your business in the direction that you want. Certainly you have to be motivated to start and finish projects on your own, but there is a kind of freedom that you probably have never felt before.
3. Work when you want:
Some people are morning people while others are night people. When you work at home, you can work whatever schedule allows you to get the most done. And if you are on vacation and want to stay a little longer, you have the ability to take that extra few days off since you make the schedule.
4. Work wherever you want:
Most work from home jobs require little supplies at all, which means you can work wherever you want. No longer do you have to worry about moving and finding a new job or getting behind when you take a vacation. If you have a laptop, you can continue working while on vacation with the click of a button.
5. More family time:
It is always rough when you work a 9 to 5 job because hardly ever is it actually a 9 to 5 job. Most times you end up working until around 6 or later and then have to deal with traffic. When it is all said and done, you are home in time to eat dinner with your family and send the kids off to bed. Now you can cherish those special times of your kids growing up and spend quality time with the entire family.
6. The sky is the limit:
Perhaps the biggest upside to work at home computer jobs is that the sky is the limit. You have the ability to make whatever you want with your business depending on your dedication and time put into it. There is no hiding the fact that it is time consuming and a lot of work to be successful, but there is nothing stopping you from continuously excelling when you work from home.

What Is A Definition Of The World Wide Web and Who Started The Phrase World Wide Web
In this article I'm going to address two related questions I've gotten: "what is a definition of the world wide web" and "who started the phrase world wide web".
First off, let me give you a definition of the World Wide Web -- which these days is usually just called The Web.
The Web is made up of millions and millions of pages of information that are linked together across the globe.
When you look at a web page, which you're probably doing right now (unless you're reading this in my free email newsletter and not on my archive of my computer articles, or on one of the free article sites I've submitted the article to) you'll find that the page has "links" that you click on to take you to different pages.
If you could see a picture of all of the web pages on the Internet, you could imagine that it might look like a spider web, with many strands connecting one point to another.
This is just how a guy named Tim Berners-Lee imagined it when he came up with the phrase World Wide Web. The links are the strands, and the web pages are the points where the strands come together.
Tim Berners-Lee, with help from a man named Robert Cailliau, created the Web based on something called "hypertext".
Hypertext was an idea where you could have "hyperlinks" (which we now just call "links") that would allow you to read information and easily move between related topics.
So if you were reading about, for example, the first printing press, the Gutenberg Bible would probably be mentioned because it's one of the best-known books to be printed on the first printing presses.
With hypertext, when you saw the words Gutenberg Bible, they would be a link to an article that would go into more detail about that book.
Berners-Lee wanted to bring this idea to the Internet, allowing people to "browse" around, using these links to move from one place to another.
Before this, you had to go to a specific address, then go to another specific address, and not browse the way we are used to today.
And as you've probably guessed by now, Berners-Lee was the person who started the phrase World Wide Web in the first place.
So another way to explain what is a definition of the World Wide Web is a way of looking at the Internet as a series of "pages" of information -- words, pictures, sounds, or video -- that link from one to another to another, forming a giant "web" of information that covers and connects the world.
One more point, to clarify a common misunderstanding. The Web is *part* of the Internet, just like email is *part* of the Internet -- a lot of people think the Internet is exactly the same thing as the Web, and that email is somehow completely separate from the Internet. This is not the case.
I have another article, available by clicking the following link, which explains the computer terms Internet and email if you need more help on those computer terms.

Choosing a Computer for Freelance Graphic Design
For many years, when a freelance graphic designer chose a new computer, Macintosh was the automatic choice. Macintosh computers provided the memory, processing speed and storage necessary for large design files. Most graphic design firms and printing companies used only Macintosh computers. Today, that trend continues but PCs are making inroads in what used to be territory exclusive to Macintosh. Therefore, the decision on what computer to purchase is not as clear cut as it once was for graphic designers.
Hardware is the first consideration of most freelance designers. While PCs have been proven to rival Macs in terms of processing speed, some people claim that Macs still process large graphic files more efficiently. Also, Macintosh computers have a better maintenance record than most PCs. However, when a hardware problem does arise a Mac can cost more to repair.
Software is where the Macintosh shines compared to the PC. All the major graphic design applications are available for both platforms and run with similar speed. However, the Macintosh operating system has historically been much more stable than the Windows operating system and much easier for the end user to troubleshoot. Additionally, Macintosh computers are far less susceptible to viruses, adware and spyware than PCs, which are notorious for their security flaws.
There are considerations beyond the hardware and software that a freelance designer needs to consider. For example, Macintosh computers typically cost more than PCs. However, once a PC is equipped with the appropriate memory, processor and graphics card to efficiently process graphic files, the cost is fairly similar. If a designer decides to switch platforms any graphic design software already owned must be repurchased under a new license which leads many designers to stick with one platform.
Aesthetics are often a consideration of many designers. Macintosh computers are designed to look sleek and creative while PCs are typically more standard looking. However, some of Macintosh's most originally designed computers are not suitable for graphic design work, leaving a designer with the standard CPU tower, monitor and peripherals, though perhaps in interesting colors.
Finally, careful consideration must be given to interactions with outside vendors and clients. Many printing companies and graphic design firms still have a strong pro-Macintosh bias and may reject native files created with PC software. However, if you are submitting EPS, TIFF or PDF files, the difference in platform will be negligible.

How To Attach An External Monitor To Your Laptop Computer
Often times you find that its necessary to attach an external monitor to a laptop computer. The most common reason for attaching an external computer monitor is to have a larger output source for a presentation. This is used when you don't have access to a projector system. Another common use of an external laptop computer monitor is to use the monitor when the laptop's LCD is not functioning properly.
Attaching an external monitor to your laptop computer is actually a very simple task that doesn't require much technical knowledge. Most laptop computers support a VGA port. This port is identical to the VGA port on a standard desktop computer. You simply plug the external monitor into the VGA outlet like you would if you were attaching it to a desktop model. That's really it.
There are, however, a few differences that you should be aware of. One difference is that a laptop computer does not always have a video signal which automates the starting of the monitor. Often times, you must use special software or keyboard commands to start the monitor.
Unlike your laptop computer monitor, the external monitor will most likely need to be plugged into an electrical outlet before it will function. Some laptops will support the running of the monitor from the battery source, but it will quickly drain the computer batteries.
Once you have attached your external monitor to your laptop computer, you will need to configure the screen. Most user's manuals will provide step by step instructions on how to do this. It usually only requires a keyboard command which should be outlined in the manual.
After you have instructed the computer about the external monitor, you will need to instruct Windows on how the second laptop computer monitor will be used. You will designate one monitor as the primary monitor and the second monitor as the back up monitor. To do this, follow these simple steps:
1. Go to your Control Panel.
2. Double-click on the "Display" icon. This will show you the dialog box for the Display Properties.
3. Go to Settings.
4. Go to the numerical icon to designate the primary monitor.
5. Go to the open box and select "Use This Device As The Primary Monitor" by placing a check mark in the box. If the box is checked for the wrong monitor by default make sure that you clear out that box.

There are, however, a few differences that you should be aware of. One difference is that a laptop computer does not always have a video signal which automates the starting of the monitor. Often times, you must use special software or keyboard commands to start the monitor.
Unlike your laptop computer monitor, the external monitor will most likely need to be plugged into an electrical outlet before it will function. Some laptops will support the running of the monitor from the battery source, but it will quickly drain the computer batteries.
Once you have attached your external monitor to your laptop computer, you will need to configure the screen. Most user's manuals will provide step by step instructions on how to do this. It usually only requires a keyboard command which should be outlined in the manual.
After you have instructed the computer about the external monitor, you will need to instruct Windows on how the second laptop computer monitor will be used. You will designate one monitor as the primary monitor and the second monitor as the back up monitor. To do this, follow these simple steps:
1. Go to your Control Panel.
2. Double-click on the "Display" icon. This will show you the dialog box for the Display Properties.
3. Go to Settings.
4. Go to the numerical icon to designate the primary monitor.
5. Go to the open box and select "Use This Device As The Primary Monitor" by placing a check mark in the box. If the box is checked for the wrong monitor by default make sure that you clear out that box.

Tips On How VoIP Internet Phone Calls Can Save You Money
One of the emerging communications technologies that is constantly improving and gaining in popularity with consumers is VoIP, or Voice over Internet Protocol. This technology essentially allows you to make telephone calls over the Internet using either your own telephone or your computer without the use of a local telephone company.
Perhaps one of the most important benefits of VoIP telephone calling is its low cost, often saving consumers anywhere from $30 - $50 a month or more on their telephone bill. Most unlimited calling plans start somewhere around $25 a month, and they allow you to call anyone in the country whenever you like, for as long as you like. If you really want to economize even further, you can also get VoIP calling plans that have a limited number of minutes for as little as $15 or $20 a month.
Obviously, if you do a lot of long-distance telephone calling, this can add up to some serious savings over the course of a year. And if you happen to make very many international calls, you'll also find significant savings in this area as well. Although international calls are not usually covered by the unlimited calling plans, the per minute rates that are charged by most VoIP providers are extremely reasonable, as low as even $.10 to $.15 a minute. And if you shop carefully enough, you can even find some providers that offer unlimited calling internationally only among their own subscribers. This could be very useful for family members who happen to live in different countries.
Another way that VoIP technology can save you money is if you happen to travel a lot. Frequent travelers can take their VoIP adapter with them on the trip and connect it to a high-speed internet terminal, allowing them to place telephone calls from their VoIP number no matter where they may be located. This can often save quite a bit of money over having to place long-distance calls from hotels or public telephones, and it can save precious minutes on your cell phone bill.
One other way that you can save money by using VoiP technology for internet telephone calls is that most VoIP providers bundle services such as voice mail, three-way calling, and so on, in with your regular VoIP plan at no extra charge. Quite often, you'll have to pay extra to get these kind of features when using a land line telephone company instead.
Finally, an added benefit of a VoIP service plan is that it is usually free of most of the taxes and regulatory fees that often accompany your monthly bill from a telephone company. Of course, that may change in the future, but for now it is savings that can be realized.
As you can see, there are quite a few ways that you can save money using VoIP technology to make internet telephone calls.

Sony VAIO Laptops - The Big Picture
History
Although Sony made computers in the 1980s for the Japanese market only, Sony withdrew from the computer business around 1990. Later, Sony re-entered the market, this time globally, under the new VAIO brand, started in 1996 with the PCV series of desktops.
VAIO Brand
The VAIO is a sub-brand for many of Sony's computer products. The branding was created to distinguish items that used consumer audio and video, as well as being conventional computing products.
One example of this was the Sony VAIO W Series personal computer, which was a regular PC and a miniature entertainment center.
Sony is expanding the use of the VAIO label. It can now be found on notebooks, subnotebooks, desktop, and a hard-disk-based audio player that comes in both 20GB and 40GB variations (called VAIO POCKET player).
VAIO Features
High-end VAIO laptops are usually shipped with Microsoft Windows Vista Home Premium or Business, while low end laptops such as N series come with Microsoft Vista Home Basic.
As of October 2005, VAIO laptops are available upon request without pre-installed software at a slightly lower price. Most recently, some models no longer ship with a Recovery CD, but a special partition on the hard drive is used for the recovery information, including operating system and all bundled software. VAIO users are prompted to create a set of recovery CDs or DVDs immediately after purchase.
VAIO computers use Intel processors, Seagate Technology or Fujitsu hard drives, Infineon RAM, Sony (usually made by Hitachi) or Matsushita optical drives, Intel or NVIDIA graphics processors and Sony speakers.
Current VAIO Models
* AR - Flagship 17" High-end multimedia machine
* FZ - The first 15" notebook with BluRay burner
* CR - New 14" derivatives of the FJ and C Series.
* BX - Professional 4:3 notebook
* G - Entry level Vista Laptop for professionals
* N - Entry level Vista laptop for home users
* TZ- 11.1" professional notebook, perfect for long business trips with 7hour battery life
* SZ- 13.3" professional notebook
Bundled software
VAIO computers feature a wide array of specially designed or bundled software that help you to use the laptop for multimedia purposes. Many of these applications inspired similar software or integration into the Windows OS, e.g. Movie Shaker preceded Windows XP's Movie Maker.
Additional software products in the bundle can include:
* Adobe Photoshop and Premiere Elements. These products are bundled as part of the video and audio integration that Sony prides its VAIO series on.
* SonicStage, a digital music manager. Integrated with Sony's Connect downloadable music service, it allows users to transfer music to Sony standalone music players, PDAs, or PSPs.
* PictureGear, an image management software that predated popular programs like Picasa.
* VAIO Zone, used for music listening, viewing photo slide shows, and watching TV (when a tuner card is present) and DVDs. VAIO Zone is an equivalent to Apple Front Row and Windows XP Media Center Edition.
VAIO Trivia
Sony named its VAIO line using an acronym for "Video Audio Integrated Operation." The VAIO logo represents a combination of analog and digital signal technology. The 'VA' represents an analog wave and the 'IO' represents digital binary code.

DSL or Digital Subscriber Line is a type of broadband Internet connection. This type of broadband Internet requires you to have a phone line. Unlike dial up, you can actually use the phone while you are connected to the internet.
What are the benefits of a DSL Internet connection? DSL allows you to have faster internet connection than a dial up. It can offer faster access to information, faster downloads and much more.
Here are some of the benefits you can get from a broadband DSL Internet service.

Students can also improve their studies by using the DSL connection. Since DSL provides high-speed internet connection, students can now research more webpage that are required for their studies.
In dial ups, low speed internet connection restricts a student’s research to just a few webpage. This is because in dial up, loading webpage is too slow that a student will just stick to one or two websites to save time and money to do their research.
Online businesses can update their websites much faster in DSL than in dial up. Updating website for online businesses is crucial to inform their customers about the products they are selling.

Computer Mouse
The computer mouse has definitely made a long journey since its inception in 1964. This input device is used for pointing and function selection. It is necessary for convenient and efficient work and play. These days it is not only used for pointing the cursor but can control almost any aspect of the PCs operation.
Computer mice are of four types - Mechanical, Optical, Laser and Trackball. Mechanical mice are the traditional ball models that are bulky and require cleaning from time to time for efficient performance. Dirt and small particles can get caught up in between the rollers and has to be cleaned using cotton and a solution. The optical mouse, however, do not function in this way and have no rollers or balls. They use an LED and sensor (unlike the ball model) to detect movement and hence dirt does not get trapped in. The modern ones use laser light instead of an LED and these give top level performance. TrackBall mouse is one in which a prominent tracking ball that reduces hand movement (thumb and finger alone involved) is provided and functions very accurately. However this type is less common.
The connection modes for mouse are - wireless or wired. The wireless variety requires a wireless receiver that has to be connected to the computer. These are ideal for portables and notebooks. There are two technologies in use bluetooth (with operating range of about 30 to 60 feet) and RF (uses radio frequency and operating range is 15 to 30 feet) Hand orientation may be symmetrical or specific, and the symmetrical one is recommended. Wired mice are connected via electric cables to either the USB or PS/2 interface whereas the wired types require AA or AAA batteries. The bluetooth mouse are similar to most wireless varieties but unlike them, these are connect to the system via bluetooth and therefore do not block valuable USB ports.
The other specifications that need attention are the buttons and wheels. USB and PS/2 ports are the commonly used interfaces. While some mice come with 2 buttons and a wheel for scrolling in the middle, some Mac mice do not have the scrolling wheel control. Some mice are specifically designed and used for gaming purposes alone are available as wireless, wired or Bluetooth. Logitech, Microsoft, Kensington are a few top names that manufacture computer mice.

Social Networks - What Are They?
Social Networks are everywhere these days - you can't fail to have heard of MySpace, YouTube or Facebook - they're three of the biggest sites on the 'Net right now. With Blogs, they are redefining the way ordinary people are using the Internet - and business has caught on to this. It's rare to go a day now without reading how any sensible Internet Marketer is making the most of Social Networking to promote their products or services.
What is a Social Network?
From Wikipedia, the free encyclopedia - A social network is a social structure made of nodes (which are generally individuals or organizations) that are tied by one or more specific types of interdependency, such as values, visions, idea, financial exchange, friends, kinship, dislike, conflict, trade, web links, sexual relations, disease transmission (epidemiology), or airline routes.Social network analysis views social relationships in terms of nodes and ties. Nodes are the individual actors within the networks, and ties are the relationships between the actors. There can be many kinds of ties between the nodes. Research in a number of academic fields has shown that social networks operate on many levels, from families up to the level of nations, and play a critical role in determining the way problems are solved, organizations are run, and the degree to which individuals succeed in achieving their goals. In its simplest form, a social network is a map of all of the relevant ties between the nodes being studied. The network can also be used to determine the social capital of individual actors. These concepts are often displayed in a social network diagram, where nodes are the points and ties are the lines. Is that clear enough? I see eyes crossing everywhere at this point in time, so I'll clarify - basically a social network is a way of illustrating the relationships between individuals - who knows who, what links they have, and so on. e.g. On the Social Networking sites I frequent, I am in social networks with all my friends, people in my region, people who subscribe to the same groups as me, and people who share my interests.
Social Network Services
From Wikipedia, the free encyclopedia - A social network service focuses on the building and verifying of online social networks for communities of people who share interests and activities, or who are interested in exploring the interests and activities of others, and which necessitates the use of software. Most social network services are primarily web based and provide a collection of various ways for users to interact, such as chat, messaging, email, video, voice chat, file sharing, blogging, discussion groups, and so on. The main types of social networking services are those which contain directories of some categories (such as former classmates), means to connect with friends (usually with self-description pages), and recommender systems linked to trust. Popular methods now combine many of these, with MySpace, Bebo and Facebook being the mostly widely used in 2007.
Why are Social Networking Sites important to Online Businesses?
Why this is important to online marketers is because they are a great way of finding people who are looking for what you are offering - say you were marketing a football newsletter, you could quickly find people interested in football via the Social Networking sites and communicate with them. By keeping your page up to date, contributing to forums and blogs, and messaging your new friends you can start to build up a relationship with other members, thus increasing the reach of your promotional messages. If you can become seen as an expert in your field on a Social Networking Site, you will soon find potential customers come to you rather than you having to find them.
One thing you need to avoid on Social Networking Sites is blatant advertising, or use of mass friend-adders or mass messaging - you'll soon find yourself deleted - as I discovered after adding some 700 people to my profile in a week, and sending them a copy/paste message. Many offer paid methods of contacting specific parts of their member base, but don't like you doing it yourself for free! So learn from my mistake and do what I do now, use them to send targeted messages to specific individuals, and when you need to communicate with large numbers at once, do it via the forums as you're intended to!
There are now many different types of Social Networking sites - the general, like MySpace, Bebo and Facebook, and the more targeted - you can find a list of business-focused social networks here So go out and join at least 3 - and start to find people who are interested in the same things as you, and the things that you are offering. Make friends, find allies, reach out to a whole new segment of your market. Social Networking Sites are an important tool to have in your arsenal today. Use them wisely.

From Wikipedia, the free encyclopedia - A social network is a social structure made of nodes (which are generally individuals or organizations) that are tied by one or more specific types of interdependency, such as values, visions, idea, financial exchange, friends, kinship, dislike, conflict, trade, web links, sexual relations, disease transmission (epidemiology), or airline routes.Social network analysis views social relationships in terms of nodes and ties. Nodes are the individual actors within the networks, and ties are the relationships between the actors. There can be many kinds of ties between the nodes. Research in a number of academic fields has shown that social networks operate on many levels, from families up to the level of nations, and play a critical role in determining the way problems are solved, organizations are run, and the degree to which individuals succeed in achieving their goals. In its simplest form, a social network is a map of all of the relevant ties between the nodes being studied. The network can also be used to determine the social capital of individual actors. These concepts are often displayed in a social network diagram, where nodes are the points and ties are the lines. Is that clear enough? I see eyes crossing everywhere at this point in time, so I'll clarify - basically a social network is a way of illustrating the relationships between individuals - who knows who, what links they have, and so on. e.g. On the Social Networking sites I frequent, I am in social networks with all my friends, people in my region, people who subscribe to the same groups as me, and people who share my interests.
Social Network Services
From Wikipedia, the free encyclopedia - A social network service focuses on the building and verifying of online social networks for communities of people who share interests and activities, or who are interested in exploring the interests and activities of others, and which necessitates the use of software. Most social network services are primarily web based and provide a collection of various ways for users to interact, such as chat, messaging, email, video, voice chat, file sharing, blogging, discussion groups, and so on. The main types of social networking services are those which contain directories of some categories (such as former classmates), means to connect with friends (usually with self-description pages), and recommender systems linked to trust. Popular methods now combine many of these, with MySpace, Bebo and Facebook being the mostly widely used in 2007.
Why are Social Networking Sites important to Online Businesses?
Why this is important to online marketers is because they are a great way of finding people who are looking for what you are offering - say you were marketing a football newsletter, you could quickly find people interested in football via the Social Networking sites and communicate with them. By keeping your page up to date, contributing to forums and blogs, and messaging your new friends you can start to build up a relationship with other members, thus increasing the reach of your promotional messages. If you can become seen as an expert in your field on a Social Networking Site, you will soon find potential customers come to you rather than you having to find them.
One thing you need to avoid on Social Networking Sites is blatant advertising, or use of mass friend-adders or mass messaging - you'll soon find yourself deleted - as I discovered after adding some 700 people to my profile in a week, and sending them a copy/paste message. Many offer paid methods of contacting specific parts of their member base, but don't like you doing it yourself for free! So learn from my mistake and do what I do now, use them to send targeted messages to specific individuals, and when you need to communicate with large numbers at once, do it via the forums as you're intended to!
There are now many different types of Social Networking sites - the general, like MySpace, Bebo and Facebook, and the more targeted - you can find a list of business-focused social networks here So go out and join at least 3 - and start to find people who are interested in the same things as you, and the things that you are offering. Make friends, find allies, reach out to a whole new segment of your market. Social Networking Sites are an important tool to have in your arsenal today. Use them wisely.

5 Tips To Help You Repair Slow Computer Speed
It seems like your computer has been losing speed lately. In fact, it's almost as if it keeps slowing down all the time! Though you hate waiting around for long periods of time for your computer to catch up to you, it just doesn't seem like you should have to shell out money for a new one just to get your old speed merchant back in gear.
Well, here are five tips designed to help you get the spring back in your computer's step and get your computer life back operating at full speed again.
Automatic Scan
Sometimes, people tell me their computer is operating really, really slow! However, after further conversation with them, I find what they mean is the computer operates really, really slow, sometimes.
When this happens, usually there is a program automatically being run periodically. When this program is being run, it is using most of the computer's resources. So naturally, the computer is going to operate very slowly. Usually such a program is a virus scanner. What makes a virus scanner so commonly the culprit is the fact Windows XP Pro, for example, makes you install a virus scanner that runs automatically every day.
To find out if this is your problem, when your computer slows down press Ctrl-alt-delete. This will open the Windows Task Manager. Click the processes tab and you can see if there is a program eating up all your CPU resources and if so, you can close that program.
If you find it is a virus scan program that is slowing down your computer, either pause the program until you finish what you're doing, or make sure the program is scheduled to be run when you're not using the computer.
The Heat Factor
Sometimes a computer can slow down because it is heating up too much. Of course, a computer that is overheating can get into much more trouble than just giving you slow performance. Therefore, is very important to keep your computer from overheating.
Every once in a while you should take the cover off your computer and blow the dust out of it with compressed air. Also, make sure your computer is closed tightly when running. If you have removed any cards from slots, make sure you have returned the hole-covers to their original places or you should cover those slots with duct tape.
The cooling system of a computer is designed to work by using a particular airflow scheme. So, leaving the cover off the computer will actually make it run hotter than having the cover on it.
Background Operations
Check your Windows taskbar, which is on the lower right hand corner of your computer screen. This taskbar consist of programs you have running in the background. If you have too many of them, they will steal your computer's resources.
Right click each of them and choose the option to suspend their operations. This is no big deal because these programs can be opened from your start menu. The taskbar just makes them automatically starting programs and, if you're low on computer resources, you don't want things running automatically.
Viruses and Spyware
The biggest resource stealer of them all is spyware and viruses. Make sure you have a good spyware/virus program and run it often. Also, make sure this program is updated frequently. There's not too much more that needs to be said about what one virus or spyware infection could do to your operating system.
Registry Clean
One of the most overlooked reasons a computer will slow down is because the registry has become corrupt. The registry is essentially your computer's operating system. Anytime you're running your computer, entries are being made and deleted from your registry. The effect this has is it leaves false entries in your registry. So, your computer's resources must work around these false entries.
Spyware and viruses leave thousands of false entries in the registry even after they have been removed. This means after you have done a spyware/virus scan and successfully removed parasites, you have to do a registry cleaning in order to remove false entries, or corruption from your registry. Not running a registry cleaner will tend to leave your computer operating at less than peak efficiency.
While there are several more reasons why a computer could be operating slowly, these five tips cover probably more than 95 percent of computer slowdown problems. Remember to take nothing for granted. If your computer should slowdown, check these things even if they seem obvious. Also, remember that a virus scan is run first and a registry cleaner is run after. Do these things, and in the order above, and chances are your computer will stay fast for a long, long time.

Know More About Computer Speaker
When Charles Babbage invented computer, it was meant for calculations and nothing else. And moreover, it was huge in size with less functioning. But technological experimentation over the years has resulted into the change in the forms and functioning of the computers. Calculation is a just a small part of the broad system; it is now the most hi-tech equipment for interaction, networking and entertainment. A computer has become a replacement of the televisions, movie theatres and as well as music players. And for all these things good quality computer speakers are required.
Computer speaker is also known as multimedia speaker that is used externally and has low power internal amplifier. Most of speakers that come along with the computer do not have good sound quality but those with better sound quality have equalization features like bass and treble that support the quality to some extent. The sophisticated speakers have a subwoofer unit to support the bass output and they usually include power amplifiers both for the bass speaker and the satellite speaker.
However, the qualities of the computer speaker depend on the manufacturer. But there are some common features too. First of all there are controls of volume and the bass and treble that support the sound. Next is the audio connection, which is 3.5mm (or1/8 inch, considered to be standard) stereo jack. Then there is a power indicator called the light emitting diode (LED) indicator.
High quality computer speaker is that, which has high frequency response, total harmonic distortion and has more watts, i.e. it should have good amount of amplification. Frequency response actually determines the measurement of amount of sound (high or low) produced by the speaker. Whereas, total harmonic distortion means the amount of distortion created by amplifying the signal. These higher quality speakers are not only used for music and movies but also are the perfect ones for multimedia and games as they provide higher quality sound effects.
Among the others, personal computers are such that are being used with greater frequency. And moreover, multimedia is one of the vital features of every computer with other software applications due to which the personal computers are more in use. Especially with increase in the use of video and the audio application in the multimedia, speakers are becoming important day by day. Most of the desktop computers and laptops usually had a single audio output, which had minimum dynamic range. Even the soundcards that are capable of reproducing high fidelity sound were absent in most of the computers.
Multimedia integrated computers have LCD display panels; CD ROM drives as well as audio speaker systems. Moreover, it also has added stereo high fidelity sound and improved sound card systems. Multimedia computer speaker system includes pairs of wide band speaker drivers mounted in different housings with amplification. It should be mentioned here that integral amplification electronics provide simple and compact transducers. This feature makes the sound quality of these speakers more exclusive and perfect for music.

Baby computer games are a useful tool for parents fostering valuable early skills in areas such as strategic thinking, socialization and collaboration, while developing basic understanding of their surroundings by identifying colors, shapes, numbers and more, associating at the same time places and names in an easier way with the aid of the games audiovisual experience.
Many parents and even educators still underestimate PC games considering them as a waste of time and irrelevant to set the basic of learning for kids during preschool age, and even considered harmful for individuals of any age. Fortunately, the percentage of adults who are convinced of the role of fun in education are higher today and the computing industry develops new digital games for both, learning and fun each and every day.
The surprising benefits of PC games have been evident over the supposed disadvantages and the branch of baby computer games offers a range of activities from early stimulation to the learning of basic skills and challenges useful for preschool children.
Most baby computer games stimulate the baby's brain development, coordination and motor skills enhancing language and problem-solving skills, making a strong bond between baby and parents because playing computer games with babies can become a pleasant family activity. Encouraging baby intellectual development is necessary but love and physical closeness is as important as the learning itself for healthy emotional growth.
Educators promote PC games as a fun activity for children and parents making a retrospective on how families were engaged though time in various activities that created stronger ties. The bedtime story tradition that still survives in many homes, the family shared time listening to popular radio shows that later evolve to watching TV together, the picnic and camping days, and so on.

Baby computer games are a useful tool for parents fostering valuable early skills in areas such as strategic thinking, socialization and collaboration, while developing basic understanding of their surroundings by identifying colors, shapes, numbers and more, associating at the same time places and names in an easier way with the aid of the games audiovisual experience.
Many parents and even educators still underestimate PC games considering them as a waste of time and irrelevant to set the basic of learning for kids during preschool age, and even considered harmful for individuals of any age. Fortunately, the percentage of adults who are convinced of the role of fun in education are higher today and the computing industry develops new digital games for both, learning and fun each and every day.
The surprising benefits of PC games have been evident over the supposed disadvantages and the branch of baby computer games offers a range of activities from early stimulation to the learning of basic skills and challenges useful for preschool children.
Most baby computer games stimulate the baby's brain development, coordination and motor skills enhancing language and problem-solving skills, making a strong bond between baby and parents because playing computer games with babies can become a pleasant family activity. Encouraging baby intellectual development is necessary but love and physical closeness is as important as the learning itself for healthy emotional growth.
Educators promote PC games as a fun activity for children and parents making a retrospective on how families were engaged though time in various activities that created stronger ties. The bedtime story tradition that still survives in many homes, the family shared time listening to popular radio shows that later evolve to watching TV together, the picnic and camping days, and so on.
Today time runs fast and for many parents is not possible to continue old traditions, but computers and the internet era have brought a whole universe of exciting family activities. PC games are classified by ages as baby computer games, toddler computer software, preschooler games and activities, etc. Regardless of the age, games are equally exciting for parents and teachers.

Laptop Buying Guide - Should You Buy An Ultra Thin Notebook Computer?
Several of the major computer manufacturers now offer ultra thin, very sleek and, above all, fantastic looking small laptops. Sony recently launched their TZ Ultraportable and in January 2008 Apple unveiled the MacBook Air. These laptops are at the cutting edge of available consumer computer technology and their unique selling point is how portable and lightweight they are. However, these are expensive laptops and the question remains - will you be getting good value for money?
The first thing to consider is exactly what you will be using your new laptop for. These ultra thin laptops maybe small, but this comes at the expense of power. They are not the most powerful laptops available because the manufacturers have had to closely pack all the components in. If you are going to be editing movies or running other power hungry applications you should go for the most powerful laptop you can get for your budget.
Secondly you should consider how much you travel with your computer, how long for and what you do with it when you do travel. These ultra portable laptops are extremely thin and particularly easy to transport, but how hard is your current laptop to carry around? For example, if you were to buy a MacBook Air you have to consider that it does not have an interchangeable battery. If you travel for long periods of time without access to power then after the battery runs out you have to wait to charge it. With a larger, more traditional laptop you could simply replace the battery with a spare one. There is a great deal of compromise in these ultra portable laptops and you need to truly assess your requirements (everything from connection ports to screen size) before committing. It may be that a laptop just ½ an inch thicker is more suitable.
Finally, there is one more important aesthetic to consider before you purchase a new laptop and that is the style factor. Ultra portable laptops are at the lead edge of personal computer technology and they look sensational. Do you want to be just another commuter with a standard laptop on the train, or would you prefer to stand out from the crowd with an laptop so compact it oozed style and design cool. The answer to that question can only be decided by you.
At Buy Macbook Air you will find a guide to the new MacBook Air, reviews and discussions about this and other thin notebook computers.

Tips on Buying Computer Monitors
A computer monitor or the Visual Display Unit is a very important part in a computer. This is where the displaying of images, data etc from the computer is done. There are various types of computer displays available in the market nowadays. Apart from the CRT displays that used to be the most used until few years back, there are Flat Panels and LCDs that are available now.
There are quite a few things to be considered before buying a computer monitor. The size is one of the factors to be considered. Sizes come from 15", 17", 19" and 21". The larger the display size, the greater the expense. A 17" is ideal where the computer is used for a considerable amount of time of more than 2 hours. For graphics art and such things, the monitor required should be 21" as it would prove useful. One thing to be noted is that even though the size of the screen could be 15", 17" etc the viewable size need not be the same. It would be definitely less than that, according to the manufacturer.
The resolution is the next thing to be considered. This is the clarity with which the picture is seen in a computer monitor. This can depend on the size of the monitor. The resolution is measured in Pixel counts. It is required to be cautious while following the ads from the manufacturers as they might give ads that are impossible to happen, for example a resolution of 1600x1200p for a 15" monitor! The ideal resolutions for a 15" screen is 800x600 or 1024x768, for a 17" screen 1280x1024, 19" screen 1280x1024 and for 21"screen 1600x1200. This is the maximum of resolution capacity by the respective dimensions.
The refresh rate also has to be considered while buying a screen. This is the number of times the screen is redrawn. The recommended refresh rate comes to 75MHz, for a standard monitor. The controls are the next thing to be noticed. Controls are the way the different aspects or features of the computer are controlled. Adjustment of different features of the monitor has to be possible, for strain-free watching and working.
There are various advantages and disadvantages in both CRT monitors and LCDs. While CRTs are quite reliable and have a longer life, they occupy lot of desk space and also are not as clear as the LCDs, who save a lot of desk space and also are not as heavy as CRT monitors, but LCD monitors have to be taken utmost care in order to have a long life. In short, monitors are of various types and forms. It depends on the user to choose the monitors according to their need and necessity

Why Is My Computer Running Slow?
Computer slowness can be caused by a variety of issues, which can be categorized in 2 categories: hardware or software. Computer hardware are the physical parts of the computer system, for example motherboard, CPU, RAM, etc. Computer software are all the programs and applications that are installed on your PC. Software includes the operating system like Microsoft Windows XP or Vista and all of the applications such as Microsoft Office, Photoshop, etc. Viruses, spyware and malware are software as well.
Things to check:
* Startup programs
* Virus and spyware scan
* Hard Drive out of space
* Fragmented hard drive
* Bad sector or corrupted files
* Overheating due to dust
Most common reason for computer slowness is unnecessary applications running in the background. When new programs & applications are installed many times they will be configured to start automatically when your computer starts.
These applications are not always needed, and will take up a portion of your computer's memory (RAM) which in turn will slow your computer down. To check what applications start automatically, clicks on the start button, then click on run, then type 'msconfig' and click on OK. Once the Systems Configuration Utility is open, click on the Startup tab. On the startup tab you can select the programs that you want to start.
Unselecting any of the programs in the startup tab will not remove them from your computer; it will merely keep them from starting automatically every time you turn your PC on. I recommend unselecting all the applications that you don't need. If you see software that you don't recognize it could be indication of virus of spyware.
If your computer is running slow and you're getting a lot of pop-up windows, even when you're not using the computer, your computer is most likely infected with a virus and/or spyware. Everybody should have antivirus software installed, updated and running at all times. There are many antivirus software packages, the best one on my opinion is Nod32 from ESET.
Regardless of antivirus software that you use, you should always keep it updated, and regularly scan your system for viruses. Most antivirus software don't check for spyware, so if your computer is infected by spyware, you should download a specialized spyware removal software. There are 2 programs that I use myself all the time, Spybot and Adaware they are absolutely free to use. Once you download and install these programs, make sure to run the updates and scan your entire computer.
Make sure your hard drive is not out of space. If it is, it's a good idea to get an upgrade, or delete some programs and files. Delete all of the temp files, temporary internet files and cookies, you could do it manually or use another free program called "ccleaner".
When files are stored on your computer's hard drive they are not always stored in the most efficient way and can become fragmented. Fragmented files take a lot longer for your system to open or save. To start the defragmentation utility click on Start then programs -> accessories -> system tools -> disc defragmenter. Defragment all of the drives listed. The defragmentation process can take anywhere from about 5 minutes to a couple of hours, and sometimes needs to be repeated. I recommend defragmenting the computer hard drive about once a month.
Another cause of computer slowness could be a corrupted system file or a bad sector on the hard drive. Bad sectors can corrupt systems files which can slow down your PC or even keep it from running.
To check and correct bad sectors run the scan disk (chkdsk) utility.
Make sure the computer is not overheating or running very warm. Most computer allow air to flow through the computer, this is great for cooling but also causes a lot of dust to accumulate inside of computer case. Dust will cause poor air circulation and might overheat your PC. Open up the case of the PC and blow all dust out using compressed air.

All About the Apple Desktop Computer
Can you even recall the days when there were no computers? If you can, then you know that back then, a typewriter was just a typewriter. Then IBM came out with the one with the ball. It was a really big deal because you could actually change the font.
The personal computer much revolutionized the way we communicate. Now the rest is history with some many applications, games; how can anyone live without a computer? Sometimes it seems as if there is only one type of computer, absolutely not true.
Like so many of us today, I have virtually been tethered to a computer for about ten years and I also thought that all computers were created equally until I began using an Apple desktop computer or Mac.
An Apple desktop computer is about the same as an ordinary computer as a horse is to a cow. The cow runs, well, like a cow. The horse (and the Apple desktop computer) is sleek and efficient, build for performance. Can you tell that I'm an Apple fan by now? Yeah? It is pretty obvious as it? The cow will do what you want it to with a little encouragement. The apple desktop computer lives to follow your commands just like the horse. The cow needs to rest and often quits working 'just because'. The Mac continues to go on and on and on because that is what it is made to do.
Daiei may think I'm just talking out my butt here but I became a true believer after a month with my Apple desktop and quickly came to the realization, it never once crashed on me. The 'cow' crashes all the time. Sure, if you worked with a PC for a long time, you'll need a period of adjustment to wean yourself away. Not that the Apple computer is hard; it is just a little bit different.
To open a file from the "finder" known on a PC as the explorer, you can't press 'return' that takes some getting use to. And here is another thing that is not the same with an Apple desktop. No viruses. I do not even own a virus cleaning system because I don't need it, although I keep a virus checker going in the background on my Apple desktop computer just in case. And what do you suppose it finds? PC viruses that have no effect on my Mac.
Another great advantage of owning an Apple computer is the automatic software updates from the Internet. It actually communicates to the Internet and automatically updates itself. No checking the website, no having to decide what you need. The complete shebang is updated automatically. Pretty cool, huh?
I always tell my pals, my Apple desktop computer is a real computer; the "other one" is nothing more than a pretender.
