Explanation:

In computing, an input device is a piece of equipment used to provide data and control signals to an information processing system such as a computer or information appliance. Examples of input devices include keyboards, mouse, scanners, [[digital camera]The]s, joysticks, and microphones.

Keyboard input

This is by far the most common way of inputting data into a computer. An application or program needs to be running to accept the keystrokes. For example a word-processing application or perhaps a command line interface for instructing the operating system.
