What is the role of peripherals in a computer system?

Peripherals play a crucial role in a computer system primarily by providing input and output functions. Input peripherals, such as keyboards and mice, allow users to interact with the computer by entering data or commands. Output peripherals, like monitors and printers, provide feedback from the computer to the user, displaying or producing the results of processing tasks performed by the system.

This dual functionality is essential for the overall operation of the computer, as it enables the user to communicate with the system and receive information. While other components in the computer, such as the CPU and memory, are responsible for processing and storing data, peripherals specifically facilitate the communication between the user and the machine. This makes them indispensable in any computer setup, as they provide the necessary means to perform both input and output operations effectively.
