Each of these languages differ by the way they communicate with a computer however, and the commands that they follow are very specific. Not a single command of one language can be interchanged with the commands or language of another. But all of them can be used to control a computer. Now it would be impossible to teach you how to program any language in a single article. 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. A virus that attaches itself to (infects) other programs is a file virus and activates the moment that an infected program starts. File viruses may also be referred to as parasitic viruses, however should a virus work from both the boot-sector and from an infected program, the virus is then known as a multipartite virus. This article will describe this recent phenomenon and describe some of its benefits for the software using community. In a nutshell, open source software is software made by everyone - for everyone. The hopes behind its development is that through its open access, it will evolve into something that represents the true desires of computer users. In today's "reality" based generation, we're always looking for the opportunity to capture and relive a moment. And we want to share that moment with others. At best, smart phones give us the opportunity to express ourselves impromptu with entertaining results. Attempting to do the same with a bulky desktop computer or laptop is to cumbersome. Automating Things with Batch Files They Work on Today's Computers Too! If you're familiar with MS-DOS at all, you'll recall that it's a command-driven operating system that performs functions issued at the C:> prompt. The only way to get an MS-DOS computer to do something was to type a command at this prompt and if you can imagine, it was a rather cumbersome way to use a computer. On a home network, each computer has access to the equipment of the better machine in the group as if that equipment were their own. Connecting computers with either an Ethernet cable or a Wireless connection can create a home network. The easiest and cheapest method uses an Ethernet connection, which requires a series of network cards, a cable for each computer, and a router.
