Lan Segment Separate LAN or collision domain.
LED Light emitting diode used for monitoring a device or network
condition.
Local Area A group of interconnected computer and support devices.
Network
(LAN)
Media Access A portion of the networking protocol that governs access to the
Control (MAC) 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.
Modal Bandwidth for multimode fiber is referred to as modal bandwidth
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.
Wire distance between two end stations in the same collision
Network
Diameter domain.
RJ-45 A connector for twisted-pair wiring.
Connector
Ports that are on separate collision domains or LAN segments.
Switched
Ports
