Hardware The Monitor is the display screen, similar to a television screen. The Computer, tower or case is the heart of the system. This is a box that contains all the parts that make the computer work. The Keyboard is what you type on, similar to a typewriter. The Mouse is the small hand held device that attaches to the computer. It may have two or three buttons. The mouse is used to move the cursor (pointer) on the computer screen.
