What is a peripheral device, and which are typical input and output devices?

• A. A peripheral is an external device connected to the computer; inputs: Keyboard, Mouse; outputs: Monitor, Printer
• B. A peripheral is an internal CPU component
• C. A peripheral is a storage device embedded on the motherboard
• D. A peripheral is a software utility that manages devices

Answer: (A)

A peripheral is any device connected to a computer that isn’t part of its core processing components. These devices expand what the computer can do by adding input and output capabilities, usually external and connected via cables or wireless links. Typical input devices are used to send data or commands to the computer, with the keyboard for typing and the mouse for pointing and selecting. Typical output devices are used to show results from the computer, with the monitor displaying the screen and the printer producing hard copies. Other descriptions aren’t correct because an internal CPU component is part of the computer’s central workings, not a peripheral. A storage device embedded on the motherboard is built-in rather than external. A software utility is a program, not a device.
