William Stallings has made a unique contribution to understanding the broad sweep of technical developments in computer networking and computer architecture

Data and Computer Communications. William Stallings has made a unique contribution to understanding the broad sweep of technical developments in computer networking and computer architecture. In over 20 years in the field, he has been a technical contributor, technical manager, and an executive with several high-technology firms.

Overall, this has been a good book from which to learn the subject. It has been updated to reflect the e in data communications. However, read with a critical mindset (ALWAYS). Almost every book has at least a few minor errors.

This is a good classic work in the field. My father has been a microwave communications technician for decades, and he praised his copy of a much earlier edition of this book. I am a mathematician picking up some computer science coursework, and have noticed a few errors in the book and accompanying solutions manual, and it surprises me that these would go unnoticed so long as to survive into the ninth edition.

The last two sentences at the bottom of page 109 contradict one another.

I discussed Problem 15.4 on page 475 with my instructor, who shared with me the approach followed in the solutions manual. In the manual, it is assumed that the average distance between stations is .375 km. The reasoning used to support this, which sounds very convincing, is in fact wrong, as average distance to a receiving station does NOT decrease LINEARLY as the transmitting station moves away from the endpoints of the bus. It actually decreases in a parabolic fashion. You can use a little calculus to show that the average distance between stations approaches 1/3 km as the number of stations increases. That's an error in estimation of 12.5%. While it makes only an insignificant difference in the context of the given problem (induces an error of less than 1% in the final solution), that error would be appreciable were the transmission speed higher or the bus longer.

The author's presentation of probability concepts in Chapter 24 leaves a lot to be desired. Figure 24.6 on page 780 is misleading. The "overlap region" should be depicted as a region on the axis, not as an overlapping of areas under probability density function graphs. My instructor shared the solutions manual answers to problem 24.4 with me, a problem involving a conditional probability computation, and the graph presented for part (a) makes no sense; probability density functions enclose an area of 1 unit ALWAYS, so the graphs of the two density functions must have identical area, which is clearly not what is presented. The misunderstanding of "overlap region" is again apparent in this solutions manual answer. What intrigues me is that the answer to part (b) given in the solutions manual is, while imprecise, essentially correct, but no explanation is given. I cannot fathom how one would arrive at the provided answer using the author's misguided notions of probability theory. Did he ask a mathematician to solve the problem, and then copy his answer into the manual? Perhaps the author could get a mathematician to contribute to the presentation of the probability concepts in the text.

Overall, this has been a good book from which to learn the subject. It has been updated to reflect the state-of-the-practice in data communications. However, read with a critical mindset (ALWAYS). Almost every book has at least a few minor errors. I can forgive most, but not the presentation of probability concepts in this book.

This book is inadequate for people without a decent amount of experience with data communications. The book regularly jumps between from extremely basic to fairly complex information making wild assumptions at the reader's base knowledge. An example of this is evident early on when the book starts by going into detail on what the parts of a wave are and then expecting you to understand Fourier Analysis to the T with very little explanation a few pages later. Charts and diagrams included in the book are referred to pages before and after they actually appear, leading to a lot of flipping back and forth. The charts are also poorly explained and detailed, often leaving out important bits of information that most people with limited knowledge wouldn't be expected to know. The review questions aren't worded well, and often leave you wondering whether or not the author had anyone from outside of his department (or even in his department) actually review his writing.

Sadly, since this is a required reading for my class, there's really nothing I could do to get away from this book. I'd assume that the majority of people looking to purchase this book are in the same position.

Honestly, I could only recommend this to people looking for a refresher on data and computer communications.

Required for Data Communication class in field of telecom. Good book but required a lot of time and dedication to fully master the subject. May not be a good idea to to take short session (summer or intercession) class with this book unless one has no other activities such as work besides the course. Will keep mine for reference.

This book is written with the understanding that the reader is well versed in the material. It bounces back and forth between an elementary subject knowledge and intermediate-to-advanced concepts. Give yourself time to read and study the material. Also, be aware that if you rent this book, you can get anything from a brand new book (which I didn't), to a bent-cornered, loosely-bound, written in copy.
  • Renthadral
Lots of material, very detailed. Some stuff is in fact to detailed, therefore hard to understand for someone new to networking.
  • Alsantrius
This is the worst textbook I have had in my entire academic career. The information is poorly organized and incomplete. The end-of-chapter questions reference topics that have not been discussed. This book is so bad I have had to control the urge to find where William Stallings works and get him fired.

Book itself is great, I received a copy with at least one page ripped out and missing.
The subject of Networking and Data communication is hard to teach and the good books are also hard to find.

For anyone interested in the details of Networking and its mathematical and logical scales, there is no other book that represents this wide subject in an easy to read, understand and comprehend the subject. Although this is only my second required textbook in the Networking and Data communication, one undergrad and now grad school, it is my ...probably 10th book to read/use as a reference in my daily tasks.

All or partial of the text might be presented as grad level course or subject, but it is presented in a simple way. Go ahead, read buy it or borrow it at the local library you won't be disappointed.
