Input Devices:
Input devices are the component of the computer system that accepts incoming data and instructions and converts them into a pattern of electrical signals in binary code that is understandable to a digital computer.
Example: Keyboard, mouse etc.

Output Devices:
Output devices are the component of computer system that converts the digitized signals into a form understandable to the user. The output devices are generally known as reverse of input devices. Output devices also send data from one computer system to another.
