I find it shocking that out of eight million comments, the top book is only mentioned ~50 times, but the parent comment illustrates why -- many people mention title/author pairs without linking to the book itself.

Code: The Hidden Language of Computer Hardware and Software by Charles Petzold (http://amzn.com/B00JDMPOK2)

Could (should?) be a class for teenagers of all kind. Sure the gradual creation of morse code could make them thrilled.

The replies to this comment are all endorsements as well and as such would not get picked up by this web-scraping. Great book though. Amazon link intentionally omitted

It's the best book to recommend for people who want a rapid introduction to computers that really provides some understanding.

It really is outstanding.

I completely agree, this book is fantastic. I read it in high school and I've been meaning to re-read it ever since.
