FULL DUPLEX
Transmission method that allows two network devices to
transmit and receive concurrently, effectively doubling the
bandwidth of that link.
GIGABIT ETHERNET
A 1000 Mbps network communication system based on
Ethernet and the CSMA/ CD access method.
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 Gigabit Ethernet. (Now
incorporated in IEEE 802.3-2005.)
IEEE 802.3U
Defines CSMA/CD access method and physical layer
specifications for 100BASE- TX Fast Ethernet. (Now
incorporated in IEEE 802.3-2005.)
IEEE 802.3X
Defines Ethernet frame start/stop requests and timers
used for flow control on full-duplex links. (Now
incorporated in IEEE 802.3-2005.)
IEEE 802.3Z
Defines CSMA/CD access method and physical layer
specifications for 1000BASE Gigabit Ethernet. (Now
incorporated in IEEE 802.3-2005.)
LAN SEGMENT
Separate LAN or collision domain.
LED
Light emitting diode used for monitoring a device or
network condition.
LOCAL AREA
NETWORK (LAN)
A group of interconnected computer 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. A set of
database objects contains information about the device.
MODAL
BANDWIDTH
Bandwidth for multimode fiber is referred to as modal
bandwidth because it varies with the modal field (or core
diameter) of the fiber. Modal bandwidth is specified in
units of MHz per km, which indicates the amount of
bandwidth supported by the fiber for a one km distance.
NETWORK
DIAMETER
Wire distance between two end stations in the same
collision domain.
