I am going into my fifth and final year as an undergraduate computer engineering student. I can say, in all honesty, and without hesitation: this is the worst textbook that I have ever used. It's hard to understand, and for all of the effort that you will put into trying to get what the author's saying, you will learn very little.
There are two main problems with the book. First, it spends too much time making analogies to non-technical systems (the pyramids in Egypt, juries in a trial, etc) without tying them into how these analogies apply to anything. There was a large section in the book that was about context: the book explained what context was with at least four different analogies, but never explained how it directly applies to computers.
The second problem is this: when the authors do speak about technology, you cannot follow what they are saying. They are either talking very far above the average person's level, or they cannot decide on one idea to stick with per sentence: I haven't decided which of these two the writing suffers from. Either way though, the result is the same: large sections are nearly incomprehensible. As an example, here is a sentence from the book:
"Programming languages that use static scope and closures provide a much more systematic scheme for modular sharing of named objects within the different parts of a large application program, but comparable mechanisms are rarely found in file systems or in merging applications such as the word processing and spell-checking systems..."
Even after reading the book and knowing what the author means by "static scope", "closures", "systematic scheme", and the rest of the technical vocabulary that litters the sentence, it's still nearly impossible to follow.
All in all, if there is any other option, I would wholeheartedly recommend that you take it. Stay away from this book.

I totally agree with the original review is 100% accurate. I have tried to come to terms with why a University would assign this text for an Operating and Networking class. It is one of the most difficult textbooks I've ever had to use for a course, it uses too many anologies that have nothing to do with the course title or the books subject matter. It has no clarity! If possible it should be give a -star rating; I can't believe it took two people to author this!
