10BASE-T The IEEE specification for 10 Mbps Ethernet over Category 3, 4, or 5

twisted-pair cable.

100BASE-FX The IEEE specification for 100 Mbps Fast Ethernet over fiber-optic cable.

100BASE-TX The IEEE specification for 100 Mbps Fast Ethernet over Category 5 twisted-

pair cable.

1000BASE-SX The IEEE specification for 1000 Mbps Gigabit Ethernet over fiber-optic

cable.

1000BASE-T The IEEE specification for 1000 Mbps Gigabit Ethernet over Category 5

twisted-pair cable.

Auto-negotiation A feature that allows twisted-pair ports to advertise their capabilities for

speed, duplex mode and flow control. When connected to a port that also

supports auto-negotiation, the link can automatically configure itself to the

optimum setup.

Auto Uplink A feature that allows twisted-pair ports to sense if a normal (MDI-X) or

uplink (MDI) connection is necessary and make the right link. It adjusts for

straight-through or crossover cables.

Backbone The part of a network used as a primary path for transporting traffic between

network segments.

Bandwidth The information capacity, measured in bits per second that a channel could

transmit. Bandwidth examples include 10 Mbps for Ethernet, 100 Mbps for

Fast Ethernet, and 1000 Mbps (I Gbps) for Gigabit Ethernet.

Baud The signaling rate of a line, that is, the number of transitions (voltage or

frequency changes) made per second. Also known as line speed.

Class of Service A term to describe treating different types of traffic with different levels of

service priority. Higher priority traffic gets faster treatment during times of

switch congestion

Collision A term used to describe two colliding packets in an Ethernet network.

Collisions are a part of normal Ethernet operation, but a sudden prolonged

increase in the number of collisions can indicate a problem with a device,

particularly if it is not accompanied by a general increase in traffic.

Endstation A computer, printer, or server that is connected to a network.
