Let us try to understand the input devices through this post of different types of input device of computer and know.

  • What are the types of input devices of computer,
  • What are the functions of computer’s input devices,
  • How and where is the input device used in the computer

So let’s know

different input device of computer

Input devices in a computer are those hardware devices that are used to give data / information to the computer,

Any computer user can only give data or information to the computer through an input device,
