LAN Cable Construction
LAN cables have a number of characteristics in common with other types of
electrical cables. All electrical cables have continuity, which means that they
serve as a complete path for electrical current flow. Each end of a cable has some
type of connector for connecting the cable to the appropriate electrical device.
Cables with multiple wires usually have a pin assignment that describes how the
wires are arranged in the connectors.
