You want a fun, entertaining introduction to computers? Get this book. The excellent pictures and diagrams clearly explain how all that hardware and software interacts in plain english. This book is good enough it can actually be a great aid in studying for A+ certification. I've met a lot of supposed "techs" who could actually gain something by reading it. When I took it to work people would laugh - until I handed it to them and they started reading. They quit laughing and many of them quickly aquired their own copy soon after.
