What type of computer is most likely to have a peripheral device?

What are the three types of peripheral devices?
Peripherals are commonly divided into three kinds: input devices, output devices, and storage devices (which partake of the characteristics of the first two). An input device converts incoming data and instructions into a pattern of electrical signals in binary code that are comprehensible to a digital computer.
What are peripheral devices why they are so called?
Computer peripherals, or peripheral devices, are sometimes called “I/O devices” because they provide input and output for the computer. Some peripherals, such as external hard drives, provide both input and output for the computer.
