Keyboard isn't used in the storage phase of a
computer-based information system
Keyboard (similar to a typewriter) is the main
input device of a computer . It contains three types of keys-- alphanumeric
keys, special keys and function keys. The function of each and every key can be
well understood only after working on a PC. When any key is pressed, an
electronic signal is produced. This signal is detected by a keyboard encoder
that sends a binary code corresponding to the key pressed to the CPU. There are
many types of keyboards but 101 keys keyboard is the most popular one.
