.
Baud Rate
It expresses the signaling rate which is defined as the change times of the status for
the electric or optical transmission medium within 1 second.
Bridge
One of network equipments which run on the layer2 in the OSI layer7 model, and it
can be connected to the LAN or network segment which uses the same protocol. It
presents the automatic network address learning and network configuration function.
Broadcast
One data packet is sent to all equipments on the network.
Broadcast storm
