KEYING DEVICES

A keyboard is a set of buttons that send coded signals to a computer, printer, or communications channel.

Each button, or key, corresponds to one or more letters, numbers, symbols, or special commands.

When you press a key, the keyboard sends a code to the computer's CPU that corresponds to the character printed on the key. When the CPU receives the signal,

it accepts it either as part of a command or as text input and later appears on your monitor screen.
