Input

In computer science the general meaning of the input is to provide or give something to the computer, in other words the state or act of a computer or a component of computer or relevant device being accepting something from the user or from a device or from a software either automatically or manually is called Input.

We categorize computer devices as input devices due to the fact that we use these devices to send instructions to the computer, we are sending our "Input" to the computer, some common examples of computer input devices are:

1. Mouse 2. Keyboard 3. Microphone

We may also call some inner parts of the computer as input components to the other components, like the power on button of a computer is an input component for the processor or the power supply. Because it takes user input and sends it to other components for further processing.
