Viruses that destroy data are known as Trojan horses, viruses that explode their attacks are called bombs, and viruses that duplicate themselves are called worms. Some viruses are a combination of each, however they can be further identified according to where they're located on a computer. A virus originating from the boot sector of a computer is a boot-sector virus and this nasty devil does its dirty work the moment a computer is turned on. Real Player and QuickTime are the first programs we think of when we think about multimedia. But Windows Media Player, also free and pre-installed, does a fine job at transmitting Internet-bound sound and video. With this application, you can easily listen to .wav files, .midi files, and even tune into a little Internet radio if you like. And it isn't fair to expect a tech support person to automatically know what a "thing-a-ma-jingy," or "whatcha-ma-call-it" is. The following describes the correct names for common components of software so that when you experience a problem, you can effectively describe an issue that you're having and a technician can readily resolve it. 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. The network card is similar to the old modems we used in the past to connect to the Internet, however in a home network, it's used to communicate with every computer that's connected to it. You'll want to first, select the computers that will connect to each other and then install the network cards inside each of them. There are a ton of resources available to walk us through computer issues but it may take a little knowledge in knowing how to access them. This article will show you how. 1. Remember help files. It's funny, but people seem to forget that every computer and every program installed on a computer comes with its own help file.
