A peripheral device is any auxiliary device that connects to and works with the computer to either put information into it or get information out of it. Usually, the word peripheral is used to refer to a device external to the computer, like a scanner, but the devices physically located inside the computer are also technically peripherals too. Peripheral devices often aren't directly involved with a computer's main function, but that doesn't mean they aren't considered necessary components.
