Without a regular maintenance schedule however, you could find out (the hard way) that a neglected computer is an energy hog - one that works harder than it needs to and one that could be a financial burden to replace. Let's talk about maintaining hardware. So much emphasis is put on maintaining a computer's operating system that we sometimes forget how important it is to maintain a computer's hardware components. 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. But we can still introduce you to some of programming's most basic concepts - starting with the commands we talked about earlier. In the not too distant past, Netscape converted its once commercial version of its Navigator web browser to open source. And today, open source is venturing into the commercial realm as well. At first thought, the idea of open source may sound just plain crazy to those who earn a living from software development. Co-workers are familiar with this temptation and they're often the ones who "share" purchased software among those who need it. However the same temptation also prompts others to knowingly or unknowingly buy bootleg copies of commercial software or registered shareware. As tempting as it is, it's still illegal and the punishments/fines for sharing commercial or registered software is too much for one to bear. 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. Each time we double-clicked on this file, the Yahoo website would load up, Microsoft Word would start, and the simple calculator would pop up. Since we want these programs to load every day, we could create a shortcut to this file and then place the shortcut inside our computer's Start Up folder. That way, these three programs would load every time we turn on the computer.
