Currently I am a CS student in my senior year. I am taking my final for the class tomorrow and the book has done an excellent job of taking some complex topics and translating them into legible english. That being said, I will just explain some of the flaws.

The first problem is the pictures or figures in book which are trying to give a visualization of the topics being explained. There a surprising amount of figures in the book that are completely horrid. I mean that they just either further add confusion or are just completely useless. Very shocking because the author/authors are very talented with words, yet seem to very bad when it comes to creating visualizations. There are a few with flat out errors as well.

The second problem is that the questions in the back of each chapter are a catastrophe. The questions are typically just very vague or just aren’t very good questions. For instance, there is a question that is similar this

“Does virtual memory need to be supported by the operating system of a handheld system?”

The answer in the teachers guide is apparently “yes”. But clearly, this answer is truly “no”. Handheld device operating systems don’t NEED to support virtual memory. There are plenty of handheld devices that don’t, and certainly you don’t ever NEED to support alot of things. The question really means to ask “Is it beneficial for a handheld device to support virtual memory?” The obvious answer that is “of course”. I got this question wrong on my homework, but myself and a few others talked with the teacher and he quickly agreed that we were right. There are just far too many questions like this that are poorly written.

Regardless of these two problems, the book is really well done.
