Glossary
repeaters and implementations that operate on fiber, thin coax
and twisted-pair cable.
Fast Ethernet
A 100 Mbps network communication system based on Ethernet
and the CSMA/CD access method.
Full Duplex
Transmission method that allows two network devices to transmit
and receive concurrently, effectively doubling the bandwidth of
that link.
IEEE
Institute of Electrical and Electronic Engineers.
IEEE 802.3
Defines carrier sense multiple access with collision detection
(CSMA/CD) access method and physical layer specifications.
IEEE 802.3ab
Defines CSMA/CD access method and physical layer
specifications for 1000BASE-T Fast Ethernet.

Defines Ethernet frame start/stop requests and timers used for
flow control on full-duplex links.
Local Area Network
(LAN) A group of interconnected computer and support devices.
LAN Segment
Separate LAN or collision domain.
LED
Light emitting diode used or monitoring a device or network
condition.
Local Area Network
A group of interconnected computers and support devices.
Media Access Control (MAC) A portion of the networking protocol
that governs access to the transmission medium, facilitating the
exchange of data between network nodes.
MIB
An acronym for Management Information Base. It is a set of
database objects that contains information about the device.
RJ-45 Connector
A connector for twisted-pair wiring.
Straight-through Port
An RJ-45 port which does not cross the receive and transmit
signals internally (MDI) so it can be connected with straight-
through twisted-pair cable to any device having a crossover port
(MDI-X). Also referred to as a "Daisy-Chain" port. The RJ-45,
10/100 Mbps port supports Auto MDI/ MDI-X.
Switched Ports
Ports that are on separate collision domains or LAN segments.
UTP
Unshielded twisted-pair cable.
