The primary device that a computer uses to store information. Most computers come with one hard drive, called drive C, located inside the computer case. See also REMOVABLE HARD DISK.
Hard drive
Desktop
On a PC, the background behind all your windows, menus, and dialog boxes, which is supposed to represent a desk. You can control whether your desktop is a neutral pattern, or a wild piece of art.
Every computer has a power supply to change the electricity from the wall outlet into electricity the computer can use. The capacity of a power supply is measured in watts. A typical computer requires 200 watts to operate. This isn’t very much, when you consider that an average hair dryer uses seven times as much power.
power supply
A little box on your screen that you click on to accomplish a task. Most buttons contain little pictures (icons) that display what they do, like a little printer you click on to print a document.
button
speaker
A device that produces sound and music when connected to a sound system. A sound system is only as good as its weakest link, so don’t hook up a good sound card to the cheapest speakers you can find. For best results with multimedia, buy speakers with a built-in amplifier and accessible controls.
