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. He has authored 18 titles, and counting revised editions, a total of 35 books on various aspects of these subjects. In over 20 years in the field, he has been a technical contributor, technical manager, and an executive with several high-technology firms. Currently he is an independent consultant whose clients have included computer and networking manufacturers and customers, software development firms, and leading-edge government research institutions.He has received the prize for best Computer Science and Engineering textbook of the year from the Textbook and Academic Authors Association six times.Bill has designed and implemented both TCP/IP-based and OSI-based protocol suites on a variety of computers and operating systems, ranging from microcomputers to mainframes. As a consultant, he has advised government agencies, computer and software vendors, and major users on the design, selection, and use of networking software and products.Dr. Stallings holds a Ph.D. from M.I.T. in Computer Science and a B.S. from Notre Dame in Electrical Engineering.

“Since most of the students in my classes are from a computer science background, teaching them the hardware and frequency domains issues is a challenge. This book [Stallings] does an excellent job in covering those topics.” — Murat Yuksel, University of Nevada “The textbook I have been using does not really do justice to the data communication core topics and I am impressed the comprehensive section provided on this topic in the Stallings text.” — Jean-Claude Franchitti, New York University “I am very impressed with both the breadth and the depth of coverage of the topics included. They meet the needs of practical laboratory assignments for a senior computer science networking class quite well.” — John Doyle, Indiana University, Southeast “I have a combination of both students who have a background in computer networks and those who have never taken a course in computer networks. All would find this book [Stallings] very useful and excellent.” — Mike Kain, Drexel University “It [Stallings] is at least at peer — if not on top — of the best textbooks I have used in networking and beyond.” — Xiaobo Zhou, University of Colorado — Colorado Springs
