Understanding Data Communications and Networks, Third Edition

Rating:
Summary: Good book for beginners
Review: Here's and excellent book for anyone who wants to learn about data communication and network systems.It uses an easy to understand language and gradually introduces a new topic.It touches all aspects of transmission modes and protocol concepts but if you want to study the seven OSI layers a better book would be Computer Networks by tanenbaum.Still a good book for beginners of the subject.

Summary: Where are the Exericise Solutions?
Review: This book explains things fairly well. I would have rated it a 3 or 4, but they forgot the most important thing: THE SOLUTIONS TO THE PRACTICE PROBLEMS!!!!! Where are they??? Without the solutions to the practice problems a technical textbook is pretty much useless!
