Input Device:

Input devices provide us a way to give input or instruct the computer to perform a function.

Keyboard

The keyboard is one of the primary input devices which helps us to interact with the computer system. The keyboard's layout is similar to a traditional typewriter with additional keys. When we press a key on the keyboard, a small portion of data is given to the computer to tell which key was pressed.
