Appendix B Glossary
Terminology 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
（
bit per second
）
.
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.
Traffic Control
It is a congestion control mechanism. The network equipment sends the data
to the equipment which has overloaded and causes the port to congest. The
traffic control can prevent the data packet from loss and avoid the
congestion for the port.
VLAN
It is the Virtual Local Area Network, which means that it takes the
network management software to establish the point to point logic
network which can cross different network segment and various network
on the switching LAN.
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 can not move toward both directions.
MDI
It is the Medium Dependent Interface, in which, one Ethernet port is taken
as the receiving terminal to connect to the port of other equipment.
MDI-X Medium Dependent Interface Cross-over
Power Over
Ethernet(PoE)
PoE is short for Power over Ethernet. To offer power supply(normally
DC) to low-consumption devices in different network part by using the
networking system.
Power Sourcing
Equipment( PSE)
Power Source Equipment short as PSE is a PoE-enabled switch and is
normally used in the root of topology.
Powered
Device(PD)
Power Devic, short as PD, is the powered devices in the end of structured
system.
