Explanation

Peripherals are used to describe input, output, and storage devices connected to a computer. The term “peripheral” means something that is on the edge or outside the main unit – in this case, outside the central processing unit (CPU).

Input peripherals include keyboards, mice, scanners, microphones, and webcams – devices that send data into the computer. Output peripherals include monitors, printers, speakers, and projectors – devices that receive data from the computer.

Storage peripherals include external hard drives, USB flash drives, and CD/DVD drives – devices that store data outside the main computer. Some devices, like USB drives, can function as both input and output devices.

Peripherals are not computer functions (which are operations the computer performs), computer types (like desktop or laptop), or methods of inputting data (which would be specific techniques rather than devices).
