Techopedia Explains Peripheral Equipment

The best examples of peripheral devices are input and output devices. Input devices are those that take external stimuli and send it to the computer for processing, such as keyboards, mice and microphones. Output devices take processed information and send it outside of the computer for human communication or inter-computer communication. This includes monitors, network adapters and printers. Internal peripheral devices, often called integrated peripherals, might include a CD-ROM drive or modem.
