5.0 out of 5 stars This is my 2nd review... Jan. 31 2002
Well, I must confess... I wrote my first review BEFORE reading any other reviews. Wow - after reading the others, I started thinking "I MUST HAVE BEEN READING A DIFFERENT BOOK!" Well, that is exactly the story. My review is of the 7th edition and I specifically went looking for the grammatical errors and the packet-switching complaints and all the other complaints, one-by-one. You know what? HOOEY!! All the problems others speak of in the 6th edition have been corrected and improved upon! This is a good book! I liked Mr. Nagle's review and the only negatives he mentions were mere weaknesses that have been beefed up. So, I still say this is a book that you'll find useful if you read it. If you want to peruse it, looking for tips and tricks on setting up your own network, then I say this is NOT the book for you - I'd look for the networking for dummies. (I'm not trying to be flipant, either. Those books only have the tips of the icebergs and are great for perusing - kinda like a cliff's notes.)
I say you will like the improvements over whatever the 6th edition missed (or messed up).

5.0 out of 5 stars why others hate this book--and why they're wrong Oct. 31 2001
This book is the ideal book for the novice networking geek wanting a general overview of communications technologies.
I just finished reading with some dismay the avalanche of negative complaints about the book. I haven't read the 7th edition, but I read the 6th edition and have a sense about the book (and by the way, note that amazon many comments are directed to that edition and not the most recent), and I have a pretty good handle on what the book is like. It looks like a school textbook because that's what it is. It's sort of boring-looking, and it even has exercises and case studies. When reading it, one is tempted to think that information is watered down, or the book is out of date or that it is useless. Because the book doesn't give a step-by-step account of how to do things, one is tempted to think it's not a good book.
But initial impressions are deceiving. When I read the 6th edition in 1999, I initially felt precisely the same way about the value of this book. (I suspect most of the negative comments here came from people who had it forced on them by a teacher for a class). The book does NOT teach you how to network or how to configure TCP-IP or how to set up your home network. What it does instead is treat pretty thoroughly communications technologies, protocols, packet technology, switches, error-checking, backbone. It discusses everything very simply and in very clear language. Also, it covers the diversity of technologies out there, including many legacy ones (and the reader may initially see this as a sign that the book is out of date--the reverse is true; this legacy information is often hard to find in a single place).

2.0 out of 5 stars Full of Contradictions and Misstatements Nov. 28 2000
It is rather surprising that this textbook is in iths 6th edition and that it is so full of misstatements and contradictions in almost every chapter. Chapter 6 is probably the worst. I am teaching from this text at a community college as an adjunct, and hence I had no input into the choice of this book. I am constantly having to type up lists of corrections to hand out to my students! Some of the errors are frankly laughable. Also, the authors do not provide an "errata" list on the Web page for this book (at Wiley Publishers), like so many authors do nowadays, recognizing the probability of errors in a textbook like this on a complicated subject.
Now, upon very close reading, I can see how so much contradictory information got into this book: There were two authors who worked on different chapters and/or sections, but they did not work closely with each other to keep from contradicting each other. The editors did a poor job in recognizing contraditions. And it seems that no one worked on providing continuity in the textbook. In the Preface, the authors thank their reviewers for their assistance, but they openly admit that this was done "often under short deadlines".
The worst mistake in the entire textbook is Chapter Eight (page 237), where they state: "Second, unlike bridges, switches don't learn addresses; switches need to have addresses defined explicitly." (They are speaking of switches that are used in LANs.) As we should well know, this kind of switch learns its address table, just as a bridge does. Could it be that the authors have confused a regular (Layer 2) switch with a Layer 3 switch?

2.0 out of 5 stars Weak points too strong July 21 2000
I agree with the other reviewers that the material is basically presented well, but that this book is outdated and too expensive for the presentation of a fairly humble amount of information. I would like to add two points. First, this book shares an all too common problem with IT books in that an editor should have taken another look at this book to catch the numerous grammar errors (notably in subject/verb agreement) and redundant passages. Second, this book has a fictional case study scenario at the end of every chapter. I found these to be poorly thought-out and not particularly helpful, especially when compared to the very informative, well-chosen actual case studies to which the authors did not devote enough time. I suggest teachers use a different book.

1.0 out of 5 stars Read page 4, 7th edition of the text
The first reading page of this text has four grammatical errors. This in itself speaks of how poorly the text must have been edited. What a rip off for the price of this book. Read more

4.0 out of 5 stars Good Book Too Expensive
This book goes through many topics from bandwith speeds to frame relay. It, however, does not cover current trends as much as it should. Read more
