Computer Networks and Internets is appropriate for all introductory-to-intermediate courses in computer networking, the Internet, or Internet applications; readers need no background in networking, operating systems, or advanced mathematics.
Leading networking authority Douglas Comer presents a wide-ranging, self-contained tour of the concepts, principles, and technologies that enable today’s Internet to support applications ranging from web browsing to telephony and multimedia. This Fifth Edition has been thoroughly reorganized, revised, and updated: it includes extensive new coverage of topics ranging from wireless protocols to network performance, while reducing or eliminating coverage of older protocols and technologies. Comer begins by illuminating the applications and facilities offered by today’s Internet. Next, he systematically introduces the underlying network technologies and protocols that make them possible: low-level data communications; packet switching, LAN, and WAN technologies; and Internet protocols such as TCP, IP, UDP, and IPv6. With these concepts and technologies established, he introduces several of the most important contemporary issues faced by network implementers and managers, including quality of service, Internet telephony, multimedia, network security, and network management. Comer has carefully designed this book to support both top-down and bottom-up teaching approaches. Students need no background in operating systems, and no sophisticated math: Comer relies throughout on figures, drawings, examples, and analogies, not mathematical proofs.

From the Back Cover:
Here's what they're saying about Computer Networks and Internets by Douglas E. Comer: "Comer provides instructor assistance, exercises, and demonstrates the concepts in an easily understandable manner. It is an excellent book, with or without a class!" — CHOICE magazine. "Comer, a recognized expert at crafting this field's textbooks, writes in a very readable and comprehensible style." — Elizabeth Zinkann, SYS Admin magazine.
"Professor Comer's book is a superb introduction to the field of Computer Networks and Internets. By far the best introductory textbook I have found of the subject." —Ivan Krsul, Professor, Universidad Católica Boliviana, Bolivia.
"A very good example of client and server code - simple enough for beginners yet illustrative of the key points." —Pradip K. Srimani, Professor, Colorado State University.
"Comer's text deals directly with technologies in wide application today, and the underlying theory... I've found it particularly useful with students who are professionals from other disciplines that need to understand the depth and breadth of networking in a one-semester course." —Stanley A. Telson, Extension Instructor, University of California-Berkeley.
"Dr. Comer has a remarkable ability to write highly technical material in a way that beginners can easily understand." —Barbara Hotta, Assistant Professor, Leeward Community College
"With Comer's book, I was able to spend a considerable amount of time on the exciting newer developments in application layer and web technology." —Javed I. Khan, Assistant Professor, Kent State University
The Second Edition of this best-selling text continues to answer the question, "How do computer networks and internets operate?" Douglas Comer, a leading computer networking authority, provides a self-contained tour from the lowest levels of data transmission wiring through the highest levels of application software, explaining how facilities and services are used and extended in the next level. Finally, the text explains how applications use reliable stream transfer to provide high-level services.
Computer Networks and Internets is appropriate for use by undergraduate students, as well as graduate students and professionals with little or no background in networking or operating systems. The text uses analogies and examples to define concepts instead of sophisticated mathematical proofs. The book's four sections cover Low-Level Transmission, Packet Switching, Internetworking, and Network Applications.
