Which term refers to input or output devices that are used to communicate with a computer?

The term that refers to input or output devices used to communicate with a computer is "Peripheral devices." These devices are essential for interacting with the computer, allowing users to input data through devices like keyboards and mice, or receive output through monitors and printers.

Peripheral devices are categorized into input devices, which send data to the computer, and output devices, which present data from the computer to the user. Without these peripheral devices, a computer would have limited functionality, as there would be no way to interact with it effectively.

In contrast, system software is the operating system and utilities that manage computer resources and provide a platform for application software. Cloud services involve computing resources and applications that are accessed over the internet rather than installed locally. Application software refers to programs designed to perform specific tasks for users, such as word processing or web browsing, but it does not include the physical hardware used for input and output.
