The IEEE specification for 10Mbps Ethernet over Category 3, 4 or 5
twisted pair cable.
The IEEE specification for 100Mbps Fast Ethernet over fiber-optic cable.
The IEEE specification for 100Mbps Fast Ethernet over Category 5
twisted-pair cable.
The IEEE specification for 1000Mbps Gigabit Ethernet over fiber-optic
cable.
The IEEE specification for 1000Mbps Gigabit Ethernet over Category 5
twisted-pair cable.
A feature on twisted pair ports that allows them to advertise their
capabilities for speed, duplex and flow control. When connected to a
port that also supports auto-negotiation, the link can automatically
configure itself to the optimum setup.
The part of a network used as a primary path for transporting traffic
between network segments.
The information capacity, measured in bits per second, that a channel
can transmit. The bandwidth of Ethernet is 10Mbps, the bandwidth of
Fast Ethernet is 100Mbps.
The signalling rate of a line, that is, the number of transitions (voltage
or frequency changes) made per second. Also known as line speed.
A device that interconnects two LANs of a different type to form a
single logical network that comprises of two network segments.
Bridges learn which endstations are on which network segment by
examining the source addresses of packets. They then use this
