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
Ω

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
Ω
and 120
Ω
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
Ω
and 120
Ω
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.
