Users Manual
C-10
Segment
A network cable terminated at both ends. Segments can be joined together using repeaters
or bridges.
Serial Data Transmission
The transmission of data over a single wire.
Shielded Twisted Pair
Twisted pair cable surrounded by a metalic shield that reduces electrical interference on
the cable. Originally referred to shielded twisted pair IBM
cable with an impedance of
150 Ω.
Skin Effect
The tendency of current to flow only near the surface of a conductor. This effect becomes
more pronounced at higher frequencies.
Split Pair
A wiring error in twisted pair cable where a wire from one cable pair is twisted with a wire
from another cable pair. Though the pin-to-pin connections may be correct, splitting the
cable pairs causes excessive crosstalk because the electromagnetic fields around the wires
cannot cancel properly.
Star Topology
A network design in which each node is connected to a central hub.
Terminator
A resistor connected to the end of a coaxial cable. The terminator, which is intended to
match the characteristic impedance of the cable, eliminates signal reflections by dissipating
signals in the cable.
Token Ring
A local area network that is arranged in a ring or star topology and uses token passing to
control access.
