SuperStack
3Com system of stackable hubs, servers, switches, routers, SDLC converters, 
and power supplies. SuperStack systems can support a range of LAN 
environments, including Ethernet, token ring, FDDI, SNA, and ATM.
Thin Ethernet cable
A cable standard for Ethernet (IEEE 802.3) networks using RG-58 A/U or 
RG-58 C/U cable and BNC connectors. The coaxial cable is 0.2 inches in 
diameter, so it is more flexible than thick Ethernet cable. Thin Ethernet 
operates at the same frequency as thick Ethernet but over a shorter distance, 
and it provides less insulation from interference than thick Ethernet.
Transceiver
A hardware device that links a node to a network cable and functions as 
both a transmitter and a receiver.
Twisted-pair
Wiring similar to that found in the telephone system, consisting of two 
insulated wires loosely twisted around each other to help cancel out 
induced noise in balanced circuits.
UTP
Unshielded twisted-pair. A cable consisting of two or more pairs of twisted 
copper wires that are not shielded.
