Keyboard Meaning

What is Keyboard:

The keyboard of a computer is one of the main input devices and is used to enter letters, symbols or numbers or commands that activate some type of program or a certain action.

Keyboards do not receive information, which is why they are called “input” or input because they only manage to send information. In a laptop the keyboard is built-in, however, in a desktop or table computer the keyboard is a peripheral as is the mouse.

The functionality of the keyboards is similar to that of the typewriters where each key pressed introduces a letter, symbol or number. The keyboard can also command different functions to the computer through the selection of a set of specific keys.
