This Fifth Edition has been thoroughly reorganized, revised, and updated. It includes extensive coverage of new topics ranging from wireless protocols to network performance." "Comer begins by illuminating the applications and facilities offered by today's Internet, and then introduces the underlying network technologies and protocols that makes data communication possible. His logical, well-organized approach helps readers understand exactly how each new technology builds on lower layers, and how the technologies fit together coherently in working networks."--BOOK JACKET. | |
