It then introduces the OSI model and then presents each of the 7 layers of this model in a separate chapter. This reference provides practical guidance methods for extending networks using repeaters, bridges and gateways; how to select and install optimum wiring configurations for specific application needs; troubleshooting and fixing the source of network malfunctions; designing and installing bus, ring and star network topologies; encrypting and formatting data; word processing, and database systems function on a LAN.
