The whole world now runs on computers. They're everywhere, from your pocket phone to your microwave oven. But, what exactly is a computer? How could you possibly build machines that calculate things, play video games, and dim the lights on command? Professor Isabella Brunel, Victorian Era Computer Expert (and a Tyrannosaurus Rex), narrates a screwball comedy romp through the fundamentals of computer architecture. The madcap cast teaches you how these extraordinary devices really work, but the book's real message is this: technology is not magic, it's created by human beings, and what other people have figured out, you can understand too.
