Broadcast
A message that is addressed to all stations on a network.
For Ethernet networks, the MAC broadcast address is
FFFFFFFFFFFF.
Broadcast Storm
A situation in which a large number of stations are
transmitting broadcast packets. This typically results in
severe network congestion. This problem is usually a
result of a misconfiguration.
Bus Topology
A bus topology is a network architecture in which all of
the nodes simultaneously receive network traffic.
Ethernet is a bus topology.
Byte
A collection of bits. A byte usually contains 8 bits.
Characteristic impedance
Characteristic impedance is the opposition (resistance
and reactance) to signal propagation on a cable. It
depends on the physical properties of a cable, which are
determined at the time of manufacture. Manufacturing
variations can cause slight differences in characteristic
impedance for the same cable type.
Client
A client is a computer that make requests of a server. A
client has only one user; a server is shared by many
users.
Collision
A collision is the result of two or more nodes
transmitting at the same time. Excessive collisions are
most often caused by a problem with the physical media.
Crossed Pair
A wiring error in twisted pair cabling in which a pair on
one connector of the cable is wired to a different pair on
the other end of the cable.
Crosstalk
Crosstalk is electrical interference generated by signal
coupling between wires in a multiwire cable.
