The central feature of this multimedia presentation is a full analysis and description in words and animations of what makes a modern personal computer tick in hardware terms. Three sections of the presentation look at different aspects of a computer: the inside with its chips and other components, the outside with its peripheral devices like the keyboard and the mouse, and the back of the machine with its connections for various devices like printers and networks. Each section has multiple parts full of easy-to-follow animations with excellent graphics. The animations are especially appropriate for showing graphically difficult topics such as how a diskette holds magnetic data and how a laser printer creates characters on a printed page. The Index feature of the program lists all of the technical terms alphabetically, from which the user can go directly to the presentation about them with the click of the mouse.
