Definition of Peripheral:
- General Use: Peripheral refers to something that is not central or of primary importance, or it can describe things that are on the edge or periphery of a certain area.
- Computing: In the context of computing, a peripheral is an external device connected to a computer, such as a keyboard, mouse, printer, or scanner, that provides input/output capabilities or enhances the computer’s functionality.
Etymology and Origin: The term ‘peripheral’ comes from the Greek word ‘peripheria’, meaning ‘circumference’ or ‘periphery’. It is derived from ‘peri-‘ (around) and ‘pherein’ (to carry). The term was adopted into English in the early 19th century, initially used in a geometrical context, and later expanded to its broader and computing-related uses.
