    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.

    The book features a vibrant full-color design with over 1,400 drawings and photographs and a clear, simple two-column format with examination techniques on the left and abnormalities and interpretations on the right. Highlights of this edition include greater emphasis on patient communication and interview techniques, a new chapter on the older adult, and over 200 new drawings and photographs of abnormalities. A front-of-book CD-ROM includes videos of head-to-toe examination. Additional student resources now available include an online e-book, more than 15 medical and nursing journal articles, and new videos including Cardiovascular: Neck Vessels and Heart, and Thorax and Lungs.
