Товч агуулга:As more and more companies begin to link branch offices, mobile workers, and telecommuters, wide-area networks (WANs) are gaining in popularity. Trouble is, WAN technology is quite different than that of the LAN systems currently in place. This much anticipated book solves the LAN/WAN dilemma faced by countless managers who are familiar with one geography and perplexed by the other. Readers will find jargon free descriptions of the most widely used LAN architectures... extension technologies such as bridges, routers, gateways, and hubs... and a survey of wide area service options including FDDI, frame relay, and ATM.
