Even the operating system of a computer has a help file and it really should be the first place to look for answers. Help files are designed not only to guide the usage of a computer, they're also designed to solve problems. Inside a help file, look for a section called, "Troubleshooting" (or something similar) when you need to resolve an issue. And this expense applies to microphones, digital cameras, PDAs, scanners, video cams, and more. Regardless of cost, it's important to understand that accessories can become "necessities," and that the best time to get them is the moment you buy a new computer.

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. 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.
