◾ How Are Computers Organized? As an interested computer user, how will this book help address my curiosity

Computers pervade many of our everyday activities. We use a computer when we withdraw money from an ATM, make purchases with a credit card, and check our voicemail. In the world around us, computers assist people in guiding airplanes, designing cars, stocking store shelves, and maintaining school records. We use computers to communicate with e-mail, to –nd information through the World Wide Web, and to type papers. We may hear people blame the computer for errors, delays, or foolishness.
