An input device is an electromechanical device that accepts data from the outside world and translates them into a form, which a computer can interpret. They act as an interface between the computer and the user. The modern computer system can take input in various forms such as text, number, sound, picture, video, etc.
The keyboard is considered the main input device in a computer system. The keyboard is just like a type-writer. The keyboard is attached to the computer system with the help of a cable. Each key of the keyboard, when pressed, sends a different signal to the processor. The keyboard has many types of keys.
