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 Gigabit Ethernet.
IEEE 802.3u
Defines CSMA/CD access method and physical layer specifications for 100BASE-TX Fast Ethernet.
IEEE 802.3x
Defines Ethernet frame start/stop requests and timers used for flow control on full-duplex links.
IEEE 802.3z
Defines CSMA/CD access method and physical layer specifications for 1000BASE Gigabit Ethernet.
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.
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.
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.
Network Diameter
Wire distance between two end stations in the same collision domain.
RJ-45 Connector
A connector for twisted-pair wiring.
Switched Ports
Ports that are on separate collision domains or LAN segments.
TIA
Telecommunications Industry Association
