Computers are everywhere, most evidently in our laptops and smartphones, but also in our cars, televisions, microwaves, alarm clocks, vacuum cleaners, and other smart appliances. Have you ever wondered what is inside these gadgets that make our lives easier and, from time to time, more infuriating? For more than 20 years, readers have enjoyed Charles Petzold's instructive story of the inner life of computers, and now he has revised it for this new age of computing. Easy to understand and cleverly illustrated, this is the book that unravels the mystery. He'll discover what Paul Revere's lanterns, black cats, seesaws, and the midnight ride can teach him about computing and how human ingenuity and our compulsion to communicate have shaped all the electronic devices we use. This new expanded edition explores in greater depth the bit-by-bit, door-to-door construction of the heart of a smart device, the central processing unit that combines the simplest basic operations to achieve the most complex achievements.
