PERIPHERAL

(Redirected from Peripherals)

:''For an account of the words ''periphery'' and ''peripheral'' as they are used in biology, sociology, politics, computer hardware, and other fields, see the periphery disambiguation page.''
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 joysticks, printers and scanners. Devices such as monitors and disk drives are not considered peripherals when they are not truly optional.
Some people do not consider internal devices such as video capture cards 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 cards qualify as peripherals under this restrictive definition, because some of them go fully inside the laptop, while some, like WiFi cards, have external appendages.
