This is the worst book I have read on any computer subject! The author does a poor job of arranging the ideas and flow in the text. The illustrations are non-standard and add nothing to the understanding of the text. On top of all that, there are parts that are just blatantly WRONG. If there were a way to put zero stars next to this book, I would do it. Do yourself a favor -- move onto the next book.
