PERIPHERAL

=PERIPHERAL= Author: Noel Lyu

A peripheral is basically just a computer device. It is not originally attached to the computer, but is a supplement to the computer. For example, the user might need to print something, but the computer doesn't have a printing device itself. Therefore, the user connects a 'printer', whch is a peripheral device, to the computer. Usually, peripherals have special connection ports, such as PS/2, and parrarel port. A peripheral could be both inside and outside the computer. For example, DVD-RW is a peripheral device, but is in the computer case. Common examples of peripherals are mouse, keyboard, printer, scanner, camera, and webcam.
