10BASE-T

The IEEE 802.3 physical layer specification for a 10 Mbps Ethernet network
over two pairs of Category 3, 4, or 5 UTP wire.

100BASE-FX

The IEEE 802.3 physical layer specification for a 100 Mbps Ethernet network
over two strands of fiber.

100BASE-T

The group of IEEE 802.3 physical layer specifications for a 100 Mbps Ethernet
network over various wiring specifications.

100BASE-T4

The IEEE 802.3 physical layer specification for a 100 Mbps Ethernet network
over four pairs of Category 3, 4, or 5 UTP wire.

100BASE-TX

The IEEE 802.3 physical layer specification for a 100 Mbps Ethernet network
over two pairs of Category 5 UTP or STP wire.

Backbone

The main transmission medium used to interconnect the workgroup areas
of a network. Fiber-optic cable is often used for the backbone connection.

CAT 3

Category 3 balanced cable. Balanced 100

and 120

cables and

associated connecting hardware whose transmission characteristics are
specified up to 16 MHz. Used by 10BASE-T and 100BASE-T4 installations.

CAT 4

Category 4 balanced cable. Balanced 100

and 120

cables and

associated connecting hardware whose transmission characteristics are
specified up to 20 MHz. Used by 10BASE-T and 100BASE-T4 installations.

CAT 5

Category 5 balanced cable. Balanced 100

and 120

cables and

associated connecting hardware whose transmission characteristics are
specified up to 100 MHz. Used by10BASE-T and 100BASE-T installations.

CDDI

Copper Distributed Data Interface. FDDI over twisted-pair copper wire.
