(coax) comprises an inner conductor surrounded by insulation. An outer conductor
wraps around the insulation, which, in turn, is covered by an outer plastic covering.
Ethernet card
A plug-in circuit board installed in an expansion slot of a personal computer. The
Ethernet card (sometimes called a Network Interface Card, or NIC) takes parallel
data from the computer, converts it to serial data, puts it into a packet format, and
sends it over the 10BASE-T LAN cable.

Hybrid Fiber/ Coaxial (HFC) system
A system where the trunk of the cable plant is of fiber technology. Somewhere
near the subscriber's home, the fiber is connected to a coaxial cable, and the

then runs through the branches of the network and is finally dropped into the
home.
