4 Network Interface Adapters and Connection Devices

Originally, LANs consisted of nothing more than computers and cables, but as the technology evolved, more equipment was required. As the early coaxial cable networks grew to span longer distances, devices called repeaters were added to boost the signals. Later, when the dominant medium for Ethernet networks shifted from coaxial to unshielded twisted-pair (UTP) cable, hubs became an essential network component. As networks grew from tools for localized workgroups to companywide resources, components such as bridges, switches, and routers were developed in order to create larger networks. Using these devices makes it possible to build networks that span longer distances, support more ...
