Fast Ethernet is a collective term for a number of Ethernet
standards that carry traffic at the nominal rate of 100
Mbit/s, against the original Ethernet speed of 10 Mbit/s.

Ethernet is the most widely-installed local area network (
LAN) technology. Specified in a standard, IEEE 802.3,
Ethernet was originally developed by Xerox from an earlier
specification called Alohanet (for the Palo Alto Research
Center Aloha network) and then developed further by Xerox,
DEC, and Intel. An Ethernet LAN typically uses coaxial
cable or special grades of twisted pair wires. Ethernet is
also used in wireless LANs. The most commonly installed
Ethernet systems are called 10BASE-T and provide
transmission speeds up to 10 Mbps. Devices are connected to
the cable and compete for access using a Carrier Sense
Multiple Access with Collision Detection (CSMA/CD )
protocol.

Fast Ethernet or 100BASE-T provides transmission speeds up
to 100 megabits per second and is typically used for LAN
backbone systems, supporting workstations with 10BASE-T
cards. Gigabit Ethernet provides an even higher level of
backbone support at 1000 megabits per second (1 gigabit or
1 billion bits per second). 10-Gigabit Ethernet provides up
to 10 billion bits per second.

Differentiate full-duplex from half-duplex.
