Minimize, Restore, and Exit buttons - these three buttons are usually located on the right-most upper part of a program's interface and each allow you to minimize a program's screen, restore it to its original size, or shut down the program completely. Scroll bar - this convenient tool allows users to move data up and down the computer screen. But the facts point to a different prediction. Open source software puts companies in a terrific position to re-brand and re-position themselves in a market that they may have not been able to reach before. In the business world, open source is all about image and when consumers witness corporations contributing (instead of selling) to the buying public, they gain big favor in the eyes of their users (plus tremendous opportunities to sell other items). You may find yourself in need of more hard drive space for all those videos and mp3s that you download, for example. Or maybe that cool new programming language you've been dying to try requires more memory than what your computer currently has. Unless the activities on your computer are restricted to pure textual output (plain text files), your computer is going to get filled with a lot of "stuff" - stuff that can overfill a PC's capacity too much for the computer to function well. But in an environment where there are five, ten, twenty or more computers, buying a license for each computer can be down-right costly. So costly that the temptation to pirate a little software here and there can be pretty tempting. Co-workers are familiar with this temptation and they're often the ones who "share" purchased software among those who need it. Even though you may use Windows XP or Vista, batch files can save you tons of time by automatically starting multiple programs and performing different tasks at the single click of a button. They don't require any extensive programming background and they don't need to be encrypted with some weird, expensive compiler. Save the individual purchases of these components for those who have more experience. 2. Decide what you'll use the computer for. If you want to use your computer for cruising the web, sending email, or performing simple word-processing or spreadsheet tasks, a computer with the basic components that we just described should suffice.
