Twisted-pair wire: UTP and STP (16-100 Mbps)
Coaxial cable: used for cable TV and connect parts of a LAN over longer distances (up to about 200 Mbps)
Fiber-optic cable: supports a quarter-to a half-million voice conversation, lighter, more durable but costly
Mbps = megabits per second
Gbps = gigabits per second
Tbps = terabits per second
