Network Tutorial

Starting with the basic precepts of networks, the book explores protocols, hardware and software components, and the unique jargon of networking. Concepts are explained clearly and simply, without assuming an extensive understanding of network internals. The glossary provides a quick reference for unfamiliar terms.

Among the many topics new to this fourth edition are: wireless networks, cable modem systems, virtual private networks, IP security, asset management, and XIVIL. Other key subjects include improving network performance, anytime/anywhere access, and interoperability.

Steve Steinke is Editor-in-Chief of Network Magazine. He has written extensively on network and systems management, collaborative software ("groupware"), server and client operating systems, and how networks affect businesses and other organizations-by making them more (and less) efficient, by failing, by exposing them to risks, by speeding them up, and by connecting them more closely to the rest of the world.
