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.

From the Author: The enthusiastic response to Computer Networks and Internets in the United States and around the world has been exciting. The book enjoys a broad appeal in both industry and academia. I have received many positive comments from readers praising the coverage of the subject, technical accuracy, and clear illustrations. For example, a manager wrote thanking me for a technical book that explained networking principles in a language he could understand.

An engineer wrote ``I love your book.' ' It is especially noteworthy that both professors and students have praised the book. In a review, one student wrote, ``At last, a text that is understandable.' ' A professor who taught a course out of the book wrote, ``I think it's great.' ' Thanks to everyone who has sent comments. The positive feedback is extremely gratifying -- it makes the long hours of effort and attention to detail worthwhile.
