Network Tutorial

Computer networks connect all types of computers and computer-related devices - terminals, printers, modems, door-entry sensors, temperature monitors, and more. For most businesses, a properly functioning network is vital to success - if the network is down, or malfunctioning, the company cannot operate. For this reason, it is important for executives and IT specialists to have at least a basic knowledge of networking. But networking is not a simple subject, and as it evolves its jargon becomes more complex and incomprehensible. Based on a popular series from Network Magazine, Network Tutorial provides a systematic introduction to all facets of networks. New subjects in this fifth edition include wireless, optical, and broadband network technologies; RAID and other network storage technologies; QOS (quality of service) over IP networks; and critical security topics such as firewalls, intrusion detection, trojan horses, and vulnerability assessment tools. Also covered are network basics, including protocols and access methods; network hardware, including cabling, servers, hubs, and Ethernet; network software, including client-server applications, network operating systems, printing, and e-mail; interoperability, including TCP/IP, Internet and web services, and LDAP; internetworking, including routers, frame relay, ATM, and remote access; and network management, including backup, fault-tolerant systems, security, and telecommuting services. This book introduces networking's basic precepts, its hardware and software components, and its jargon. Concepts are explained in easy-to-understand terms. The glossary provides a quick reference for unfamiliar words.
