Reference
The types of Ethernet standards are summarized below.
Segment
A “segment” is a unit of a LAN. It normally refers to the range of a single cable.
Type Standard
Reference
Gigabit Ethernet
“Gigabit Ethernet” is a high-speed Ethernet standard that delivers faster communication speeds of one gigabit per
second ( 1000Mbps ) . There are a
number of variations for this standard
including 1000BASE-T that uses twisted
pair cable, and 1000BASE-LX that uses
fiber optic cable.
Reference
Switch
A “switch” is a type of network device
that connects networks, and refers to a
line concentration device that houses
twisted pair cable used for 10BASE-T
and 100BASE-TX.
Fast Ethernet
“Fast Ethernet” is a high-speed Ethernet standard that delivers faster communication speeds of 100Mbps. There
are a number of variations for this
standard including 100BASE-TX that
uses twisted pair cable, and 100BASEFX that uses fiber optic cable.

Reference
Backbone LAN
A “backbone LAN” is a LAN for connecting multiple LANs in which computers
are directly connected, operating them
together as a single network. A backbone LAN must be fast and reliable,
and have a large capacity.
