Sure, computer stores do their best to keep their inventory up to date, but when you can download version 5.6042 of a shareware program as opposed to buying a commercial 3.0 version from the local computer shop, there's just no comparison. Which brings up our next point. Just where does one get shareware? Fan sites probably isn't a good name for this resource, but you can find websites that are dedicated toward supporting the users of a particular software program or piece of hardware. We've called them "fan sites" because the maintainers of these sites have no affiliation with the manufacturers that they support! The commands in a program are pretty useless unless they have some data to act on so programmers either give the programs some data to work with (list of names or numbers for example) or they make the program generate it's own data. Sometimes, the data comes from an outside source like the Internet or the computer that the program runs on. Although it's a rare occurrence, hacking has become the biggest criminal nuisance in computer history. Make no bones about it. There's nothing innocent or cute about the hacker. Today's hackers aren't the pimply-faced teen rebels that you might be thinking of. Instead, this generation of hackers are grown individuals who are more than likely earning a living by stealing the identities of innocent, law abiding individuals and then selling those identities to others who want to slip by the system. A Few Common Computer Errors (And What They Mean) Computer errors can pop up when least expected, they can cause the entire system to suddenly shut down, and they can inadvertently corrupt data to the point where it can't be deciphered. Although they can't always be avoided, it's important to remember that computer errors can be corrected. File compression combines a number of different files into one file, and it can also significantly reduce a very large file to a smaller one. As a result, the transmission of a compressed file across the Internet is faster and smoother. This article looks at compressed files a little closer and it describes how to compress and decompress them using two of the most popular archiving programs.
