====== Peripheral Device ======
[[dido:public:ra:xapend:xapend.a_glossary:start| Return to Glossary ]]

A **Peripheral Device** is an internal or external device that connects directly to a computer or other digital device but does not contribute to the computer's primary function, such as computing. It helps end users access and use the functionalities of a computer.

Since it’s not a core device for the system, the computer can still function without the peripheral, which simply provides extra functions. However, some peripherals such as a mouse, keyboard, or monitor tend to be pretty much fundamental to the interaction between the user and the computer itself.

A peripheral device is also called a **Peripheral**, **Computer Peripheral**, **Input-Output Device**, or **I/O Device**.
