Explanation
10Base‐T
Twisted‐pair standard of Cat3, Cat4 and Cat5 in IEEE specification for
10Mbps Ethernet
100Base‐TX
Twisted‐pair standard of Cat5 or above in IEEE specification for
100Mbps Fast Ethernet
100Base‐
Ｆ
X
Fast Ethernet which uses one pair of multi‐mode or single mode
optical fiber to transmit.
Adaptive
A characteristic that is automatically configured to adaptive mode for
the speed, duplex and traffic control port.
Bandwidth
The information capacity that the channel can transmit. For instance,
the bandwidth of the Fast Ethernet is 100Mbps

.
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
Restless forward broadcast frame or multicast frame on bridge
caused by the bridge ring.
Full Duplex
Use switches to set up the point to point connection among nodes in
the LAN and allow them to receive and send data packet at the same
time.
Half Duplex
The communication for two nodes can only move toward one
direction at the same time, but cannot move toward both directions.
