Does avg slow down your computer?
I must disagree with David. I have been in the computer sales and service field for over 25 years and must say that I have found Avast to be one of the worst antivirus programs on the market, surpassed only by AVG in its ineptitude. The programs that I recommend and sell to my clients at this point is Kaspersky Antivirus.
To answer your question directly, yes, Avast can slow down your machine as it can be set up incorrectly to do more scans than are necessary. Just like what Norton Antivirus allowed people to do about a decade ago (which is what soured people against their software), Avast can be set to scan files each time they are accessed, created, edited, deleted, or closed or some combination of these various file operations. Some people feel that having the software scan files at all stages of file operation is advisable and necessary. Doing so means that it can bring a machine to a crawl. In the most extreme example, I once saw a client's machine take over half an hour just to boot to the desktop. Most antivirus programs do not allow access to those options precisely for this reason. Instead, they allow the configuration of what should be scanned (Smart Scan (it selects the appropriate files to scan), Extension List (it scans files based on a certain configurable list of extensions), or user-configurable (the user gets to set whatever he wishes to have scanned).
Also, Avast can slow down your machine indirectly because of the multitude of infections that it fails to detect. It is not uncommon for me to have a machine come in that is allegedly protected by Avast and the user is complaining about the machine not working correctly or running slowly and when I scan it with Kaspersky, I find up to 3000 infections that were missed. Once those are removed, even if Avast is left on the machine, the machine works worlds better, though after showing easily that Avast is inferior, most clients ask me to put on Kaspersky, after which they do not have problems anymore.
If you are looking for an antivirus that is better than Avast and do not wish to pay for a commercial product, then I recommend Avira. You can get their free product at http://www.avira.com/en/avira-free-antivirus I have recommended and used them for certain clients over the years and while it is not as good as a commercial product (you get what you pay for, after all), it is definitely the best of the freebies.
If you have any other questions or need further advice, feel free to drop me a line.

Is building a computer more expensive than buying one?
For many years, purchasing parts for a computer could offer a significant cost saving. In 2010, that appears to be no longer true. Pre-assembled hardware has fallen in price steadily and as most computers are supplied with an operating system installed, there is no additional cost for OS licenses.
The reason to build your own computer should be based on specific functionality that you require rather than just financial. If there is any cost saving it will be minimal and should there be problems with any of the hardware, warranties are not as effective for individual parts. No parts supplier will be willing to offer on site repairs whereas many system suppliers offer on site service as part of the deal.
1 bit is the smallest amount of information that can be stored 1/0 on/off
1n = 4 bits ( nibble )
1b = 8 bits
1w = 16 bits
1lw =32 bits
1d = 64 bits
1f = 64 bits
1K = 1024b
1mb = 1024k (1024 * 1024) bytes
1gb = 1024mb
Hope this helps

Where can pictures of computers be viewed?
The Free Digital Photos website has pictures of computers. If one wants a picture of a current model, then one will find a picture on, for example, Amazon's site. For pictures of older machines, such as the IBM 7094, the Google images library is the best place to visit.
What is a computer rack typically used for?
A computer rack is a frame or shelving unit that is usually made of metal. It is used to hold different pieces of computer equipment such as servers, hard disk drives and modems.
A kilobyte is 1024 bytes. A megabyte is 1024 kilobytes. A gigabyte is 1024 megabytes.
So, 1,000 megabytes X 1024 kilobytes/megabyte = 1,024,000 kilobytes.
1,024,000 kilobytes X 1,024 bytes/kilobyte = 1,048,576,000 bytes. You also might want to check out mebibytes, gibibytes, and the like.

Can computer games make you dumb?
If you don't miss out school and other activities than no. Computer Games also contribute to different skills.
If the intermediate code generated is the same for all the machines. Hence the
number of Front end conversions is one for each language. Similarly the number of
back end conversions is equal to the number of machines.
Intermediate representation has a variety of forms. There are also many algorithms for
generating intermediate codes for typical programming language constructs.
To generalize, for M languages on N machines we would require M Front end
conversions. The number of back end conversions would then be equal to N*M.

What is the full form of FAT in terms of Computers?
FAT is a file system used by MS-DOS and other Windows-based operating systems to organize and manage files.

Windows stores information about each file in the FAT so that it can retrieve the file later.
How do you write on the computer?
Assuming you mean typing, you would need a word processor or at least a simple document editor. Windows comes with Notepad and WordPad. Notepad is quick and dirty, while WordPad has more functionality. Those are sufficient for many things. Or you can install something like Microsoft Word or Open Office. Then you would use the printer for printing your documents.
