Examples of input devices

What are input devices? They are also called input peripherals, and refer to the equipment and components used to enter or provide a multitude of data and control signals to the processing unit and then be able to work with them. Although this concept generally implies “additional but not essential”, on many occasions they are very important elements, we would even say essential, for a computer system.

Some of the most outstanding features are:

  • They are part of the hardware , which includes the computer chassis, cables, fans, peripherals, etc.
  • They receive a lot of information in audio, image or text , provided by the user and transmitted through the computer.
  • They are very easy to use and, as technology advances, they are updated.
