- A peripheral device is an internal or external device that connects directly to a computer but is not essential to its primary function of computing. Peripherals can be input devices, output devices, or storage devices. - Peripheral devices include items like mice, keyboards, monitors, printers, scanners, webcams, and more. They can be either external devices that connect to the outside of a computer or internal devices installed inside the computer case. - Peripheral devices help users access and utilize a computer's functionality. Some devices like modems can serve as both input and output peripherals.

Three general categories:
1. Input devices
2. Outputdevices
3. Storage devices
An output device reverses the process,
translating the digitized signals into a
form intelligible to the user
