What are computer peripherals categorized as?

Computer peripherals are categorized as both input and output devices because they serve essential functions in the interaction between the user and the computer system. Input devices, such as keyboards and mice, allow users to send data and commands to the computer. On the other hand, output devices, like monitors and printers, enable the computer to convey information back to the user.

Some peripherals can perform both functions; for example, a touchscreen monitor can receive input when a user touches the screen while simultaneously providing output by displaying visual content. This dual capability of various peripherals emphasizes their role in facilitating user interaction and enhancing the overall functionality of a computing system.

In contrast, options that limit peripherals solely to input or output functions do not reflect the versatility and multifaceted nature of computer peripherals in modern systems. The definition of peripherals as integral components that support both types of interactions captures the broad spectrum of devices connected to a computer.
