GLOSSARY
Modular Plug — EIA-standard connector used to terminate twisted-pair
patch cables and equipment cables. Sometimes called RJ-45 plug.
MSAU (Multi-Station Access Unit) — A Token Ring wiring center for
network attachment.
MTBF (Mean Time Between Failures) — The average operation time to
component failures.
Near-End Crosstalk (NEXT) — Noise coupled between two twisted pairs
measured at the same end of the cable as the disturbing signal source.
Network — A collection of nodes interconnected by a medium.
Network Interface Card (NIC) — The circuit card that interfaces a station
to the network.
Network Manager — A program that is used to monitor, manage, and
diagnose the problems of a network medium.
Node — Connecting point on a network. A station or device on a network.
Noise — Any random disturbance in a communications system that
interferes with the integrity of the transmitted data.
NVP (Nominal Velocity of Propagation) — The speed of signal propagation
through a cable, expressed as a percentage of the speed of light in a vacuum.
Ohm — The unit of measurement for resistance.
Open — A break in the connection between the two ends of a wire or cable.
OSI (Open Systems Interconnect) — A seven-layer architecture that serves
as a model between systems.
Packet — A group of bits in a defined format, containing data and control
information used for transmission from one node to another.
Pair — Two wires in a multi-wired cable that are used as a single
transmission path.
Passive Concentrator — A type of Multi-Station Access Unit (MSAU) used
to connect stations to a Token-Ring network without signal regeneration.
