INTRODUCTION
Whenever you hear or see the word microcomputer, you probably think of a personal computer. A personal computer is, of course, one type of microcomputer. But you may not be aware of other forms of microcomputers. For example, do you know that almost every piece of electronic equipment you own or use has a microcomputer in it? This type of microcomputer is called an embedded controller. It is usually a single integrated circuit that performs all of the basic functions of a computer but is dedicated to a specific task. Such micros (micro is short for microcomputer) are in TV sets, stereo receivers, microwave ovens, CD players, DVD players, cell phones, blenders, copiers, and most other types of electronic devices. You will find them in your car (several of them), your iPod, your bathroom scale, gasoline pumps, and dozens of other things you use every day. Microcomputers do indeed make your day—you cannot live without them.
