LAN cable is a high - speed data network cable. It typically connects workstations, personal
computers, printers, servers, and other devices and offers computer users many advantages, including shared access to devices and applications, file exchange between connected users, and communication between users via electronic mail and other applications.

Plenum cable is coated with a fire-retardant coating (usually Teflon) so that in case of a fire it does not give off toxic gasses and smoke as it burns.
