Peripheral
A
peripheral is a type 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 though some form of
computer bus like
USB. Typical examples include joysticks,
printerss and
scanners. Devices such as
monitorss and
disk drives are not considered peripherals because they are not truly optional, and video capture cards are typically not referred to as peripheral because they are internal devices.
