For an account of the words A peripheral is a piece of Computer Hardware that is added to a host Computer in order to expand its abilities. More specifically, the term is used to describe those devices that are optional in nature, as opposed to hardware that is either demanded or always required in principle. The term also tends to be applied to devices that are hooked up externally, typically through some form of Computer Bus like USB . Typical examples include Joystick s, Printer s and Scanner s. Devices such as Monitor s and Disk Drive s are not considered peripherals when they are not truly optional. Some people do not consider internal devices such as Video Capture Card s to be peripherals because they are added inside the computer case; for them, the term peripherals is reserved exclusively for devices that are hooked up externally to the computer. It is debatable however whether PCMCIA Card s qualify as peripherals under this restrictive definition, because some of them go fully inside the laptop, while some, like WiFi cards, have external appendages.
