actively cool It helps the heat sink by blowing air

through it.

Hard Drive computer hardware that holds and spins

a magnetic or optical disk and reads and writes information on it It has the ability to store data

permanently

Video Card A circuit board in a computer system

designed to generate output for the system's video display screen. A laptop’s is usually soldered to the motherboard

Output device

electronic or electromechanical equipment that connects to a computer and used to transfer data out of the computer in the form of text, images, sounds, or other media. This can be printed documents, sound,

and video projection

Input devicesa device that can be used to insert data into a

computer or other computational device, to be used later in various processes

SOFTWARE Any written program or procedures or

rules and associated documentation pertaining to the operation of a computer system and that are stored in read/write memoryThis can be a game, DOS, or programs
