what is input and input device?
Answers
An input device is any hardware device that sends data to a computer, allowing you to interact with and control it. The picture shows a Logitech trackball mouse, which is an example of an input device.
The most commonly used or primary input devices on a computer are the keyboard and mouse. However, there are dozens of other devices that can also be used to input data into the computer.

Input is command that given to any machine to do any task. And device which used to give input is input device.
Ex - If you switch on the bulb then you give input ON to bulb to glow and switch is input device that you used to give input.
