Like the mouse, the keyboard is an input device that allows you to talk to the computer. The keyboard is easily recognizable because it resembles a typewriter keypad. If the typewriter predates you, then look for the component that's covered with buttons that have letters, numbers, and symbols on them. If you've ever used a typewriter, you probably recognize many of the keys on a keyboard. In any case, the alphanumeric, symbol, and punctuation keys are self-explanatory. and we'll review the rest of the keys that are unique to a (101-key and 104- key) keyboard. However, we will ignore the three keys found above the numeric keypad (<print screen/ Sys Req>, <Scroll Lock>, and <pause/break>) because they are all fairly useless on most computers today.
Note: If you keyboard includes multimedia and Internet buttons above the keys, consult the manual that comes with your keyboard to learn their functions.
