Customer Book Reviews
I'll make two separate sets of comments - one for professors and one for students. Students first... Forouzan is about as easy to read as any book on the subject. Since Forouzan has done a pretty good job of keeping the text up-to-date, however, you may find it difficult to use a previous edition of the text. I would estimate that about 20% of the material is either new or revised in the 3rd edition. The website also has some pretty good student resources, such as notes and related study tools. For professors... I have been using the text since its first edition and have no regrets. In the third edition, Forouzan departs from the 7-layered OSI model to something he calls the 5-layered Internet model (Application, Transport, Network, DL, Physical), which may not be 'standard', but it certainly makes things a little easier when talking about the Internet and modern computer networks. There seems to be enough quantitative material to satisfy those who wish to take a more engineering-centered approach to data comm, although I'm not sure how this text would fly in a school of engineering (my home is a school of business). There are ample online resources for professors, including powerpoint shows and exam materials. The only other text I would consider as a substitute for Forouzan is the slightly more technical text by Stallings, but as I said, I have never had any regrets about Forouzan.
I'll preface this by saying I'm only on page 102 of the book, but I have to agree with a previous user about the annoying errors. I bought this book to study on my own and test out of a college prerequisite class. Some things are crystal clear, but there are places where he'll state one thing and contradict himself later on. One example is in chpt. 4 discussing line coding. First he states that for NRZ-L positive voltage usually means the bit is 0, while negative voltage means the bit is 1. In the next section he states 'Like NRZ-L, positive voltage means 1 and negative voltage means 0.' Which is correct?!? In addition, there are places where he'll refer to a topic or equation and state that he discussed it before when he didn't. For someone who has no background in this at all and no way to ask questions, these errors and contradictions are very frustrating. It's a compehensive book, but it's time for a new edition or, at the least, an online errata page.
This book gives full coverage of all of the basics of data communications including signals, modulation, transmission media, and ECC. It has a comprehensive coverage of OSI and networking protocols with illustrative details of packet and frame contents with emphasis on the first four layers. There is coverage of most important networking technologies including TCP/IP, ATM, ISDN, frame relay and SONET. The many illustrations are appreciated. The book is well written and easy to follow and has excellent breadth of coverage but it does not develop theoretical aspects or mathematics in areas such as modulation or traffic modeling. I am considering adopting this text for a second-year computer science course.
I teach a second year under-graduate (degree) course in Data Communications and Networking. This is the first networking paper that students will take. I have used Shay, Stallings and Tanenbaum in the past but have changed to Forouzan because I believe that it does an excellent job of introducing concepts at a level that is readily understood by a novice. Student feedback confirms that it is about the right level and that they feel they actually understand the text - quite a bonus ;-) Another review recommends the above authors - and I agree they give an excellent treatment of the topic - but they require an advanced student. I would select Stallings or Tanenbaum for a paper that follows the introductory paper (we actually use Comer for the advanced paper which is specifically TCP/IP) Forouzan's 'Data Comms and Networking' is clear, plainly written - yet gives a good depth to the topics being considered. The diagrams and practice questions are excellent. I highly recommend this book for an introductory under-graduate text.
I am currently teaching a class using this text. I think that it is OK- but I personally would prefer Stallings or Tanenbaum. Stallings and Tanenbaum are much more engineering or technically oriented. I have come across a number of small annoying errors in Forouzan's text, as well as a number of opinions that he puts out as facts. Of course I wouldn't be annoyed if his opinions and mine agreed - but he could at least properly identify them. This mostly is a problem with what technologies are 'winners' or 'losers' in the marketplace, or what dificulties are presented with trying to implement some of the protocols mentioned. If you want to know how stuff really works go with Stallings or Tanenbaum. If you want to know how to communications is used by a business - there are a number of other texts that are far better. I feel like this text is half-way in between. Unfortunately I am unable to change what text we are using here...
Forouzan made another noble work! This textbook is one of my first group of books in computer networking area. I finished reading this book 2 years ago. It has a clear text, very friendly and easy to read. I highly recommended this book for everyone interested in Computer Network, especially a student.
My choice for the text in a single networking course for CIS majors
By Charles Ashbacheron Nov 11, 2008
Several years ago, I unexpectedly found myself teaching a two-course networking sequence in a Computer Information Systems (CIS) program. After one pass through the sequence, I began lobbying for a change to a single networking course. My goal was to drop the more technician-level material in favor of a course where the concentration was on data communications and the structure of the protocols used to do it. Some of this is my personal preference for the applied theory aspects of computing, but the majority was due to the fact that most students were not very interested in technician level material. This book is the perfect one for my ideal of the single course. The material is segmented into seven parts, based on the layered Internet model. The parts are: *) Overview of data communications and networking *) Physical layer *) Data link control and protocols *) Network layer *) Transport layer *) Application layer Each part is then segmented into chapters where specific features and protocols of that layer are discussed. For example, the application layer part is constructed of the following chapters: *) Client-server model: Socket interface *) Domain name system (DNS) *) Electronic mail (SMTP) and file transfer (FTP) *) HTTP and WWW *) Multimedia *) Cryptography *) Message security, user authentication and key management *) Security protocols in the Internet The coverage of each of the specific features is very technical; the field structure of all the protocols at all levels is covered in detail. At the end of each chapter, there is a small set of short answer review questions, a set of multiple-choice questions and a set of exercises that require detailed answers. If I am ever able to realize my dream of converting to the single networking course, this will be the textbook that I use.
This is an outstanding book on data networking, probably the best-in-class in its category of the 10-15 competing alternatives that I've seen. The book can be used both as a textbook in a college course on networking as well as a reference book for a working professional. The clarity of the writing is exceptional. In addition, nearly every page of narrative contains one or two diagrams that help explain the concepts discussed in the narrative. Each chapter closes with a one-page list of key terms and concepts, a thorough two-page bullet-pointed chapter summary, and literally scores of review questions and exercises. All of this makes the book ideal as a course textbook. The only problem is the book's price. It's just too darn expensive. If your employer is going to pick up the tab, then obviously price is a non-issue. However, if you have to shell out your own money for it, hold out until you can find a copy for $40 or less, which I think is a fairer price. Although this book was published in 2001 and two subsequent editions have been published since then, it still is a worthy selection for classroom use and will remain so for another 5-6 years.
This book is one of the great texts on the subjects covered. It has been a required text for two undergraduate and one (so far) graduate class that I have taken. Mr. Forouzan's prose is clear and his examples understandable. The only thing that might make portions of this book a difficult read for some people is the complexity of some of the material covered. The book starts at the electrical (Manchester encoding, NRZ, etc.), and gradually builds until the networking process is clear, top to bottom. In terms of completeness, I have not seen another book that covers everything from the LAN to the WAN like this book. Also included are related topics like cellular networks, PSTN, encryption, and even the application layer of the OSI model. The complete OSI model is covered with great depth.
~Although the price of the book is outrageous, the content the author put into is worth the money well spend compared with other book series. Though the book starts at laymans' terms, it progress to more detail and exciting about communications, and I especially like the author's discussion about digital bit transmissions, which is the best I awared of compared with others (Tanenbaum, Comer, Stalling, etc). The appendix for Fourier Series really stands out for readers who are deep serious to~~ apply the knowledge with '1's and '0' to new perspective.~
My major is computer science but this book almost made me seriously consider choosing a different area. I thankfully didn't but I came pretty close. Why? Extremely poor explanation of topics, lack of good examples, and just an overall lack of engagement with the reader. I know the goal of a textbook like this isn't to entertain the reader, but at least make the material interesting and meaningful. Because it is, it's just the way the topic is presented here makes it so difficult to learn what is being taught that I doubt most people will find this book a good learning experience.
Thanks
Page quality is not up to standard. But Overall book was totally brand new which I should admire.
The book is in perfect condition and is very affordable for students. There are no bookmarks. I love it and hope to get an A after reading this book :)
The book is in very good condition
Good textbook; complex content but explained as straightforward as ...
By Mockeryon Nov 12, 2014
Good textbook; complex content but explained as straightforward as it can be. In good condition. Note; AMERICAN VERSION. NOT INTERNATIONAL. In my case, that was what I wanted.

Great condition, great buy, great everything. Will order from this place again. I was skeptical about ordering a used text but this wasn't bad at all.

5 Star. All Good.
used for school, purchased at a discount rate here on amazon so it was certainly worth the money and it served it's purpose.
