Executive Summary

Traditional copper-wire based Local Area Networks (LAN) (copper LANs) send high-speed radio frequency signals between a hub and individual computers. In turn, the signals from the multiple hubs are accumulated at a switching/processing machine at a main communications room. The multiple hubs are generally Ethernet switches connected by copper wires to the computers. The main accumulator is an Ethernet switch with fiber optic or copper connections to the hubs.
