  Lantronix Fast Ethernet Tutorial: Fast Ethernet and Gigabit Ethernet Technologies
Between Ethernet switches, Fast Ethernet repeaters are used to connect a group of switches together at the higher 100 Mbps rate.
In the terms of Fast Ethernet, essentially 200Mbps of throughput is the theoretical maximum per full-duplex Fast Ethernet connection.
Fast Ethernet ports on Ethernet switches are used to provide even greater bandwidth between the workgroups at 100Mbps speeds.

Ethernet versions 1.0 and 2.0 followed until the IEEE 802.3 committee re-jigged the Ethernet II packet to form the Ethernet 802.3 packet.
Ethernet 1.0 did not have this in its standard and 802.3 says that repeaters must not connect to a transceiver that generates the SQE test because of the Jam signal that is designed to prevent redundant collisions from occurring.
Ethernet relies on electrical signalling to determine whether or not to send data, so a faulty card could stop all traffic on a network as it sends false signals causing other devices to think that the network is busy.

Fast Ethernet introduces a number of new functional layers to the physical layer.
The traditional Ethernet preamble has been modified to allow the receiving station not only to sync up to the transmit clock on each pair, but also to notify the receiving station of the pair transmit order, so each frame can be re-assembled in the proper order at the receive end.

 Fast Ethernet (Linktionary term)
During the early development of Fast Ethernet, two different groups worked out standards proposals-and both were finally approved, but under different IEEE committees.
The primary concern of Fast Ethernet developers was to preserve the CSMA/CD medium access method of 802.3 Ethernet while boosting the data rate.
They detect improper signals, perform data translations between different types of Fast Ethernet, monitor the network for faults, disconnect faulty ports, and partition off part of a network that is having problems so that the network can continue running.

 3Com Technical Papers: How Fast Are Ethernet Networks?
Fast Ethernet is identical to Ethernet, only ten times faster at 100 Mbps.
To upgrade an Ethernet network to Fast Ethernet, you need to deploy: 100 Mbps switches or hubs; NICs (network interface cards), which are cards that fit into each computer and determine how fast the device links to the network; and Fast Ethernet-capable cabling.
When upgrading your network to Fast Ethernet, replacing a switch or hub is relatively easy; replacing the NICs in every computer is time-consuming and installing new high-speed cabling can be costly.

 Fast Ethernet - Wikipedia, the free encyclopedia (via CobWeb/3.1 planetlab2.cs.unc.edu)   (Site not responding. Last check: 2007-11-02)
In computer networking, 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.
Introduced in 1995, Fast Ethernet is no longer the fastest form of Ethernet: gigabit Ethernet and the new 10 gigabit Ethernet standards are 10 and 100 times as fast, respectively.
The data signaling rate actually observed on real networks is far less than the theoretical maximum, due to the necessary header and trailer (addressing and error-detection bits) on every packet, the occasional "lost packet" due to noise, and time waiting after each sent packet for other devices on the network to finish transmitting.

 Ethernet
The original Ethernet was developed as an experimental coaxial cable network in the 1970s by Xerox Corporation to operate with a data rate of 3 Mbps using a carrier sense multiple access collision detect (CSMA/CD) protocol for LANs with sporadic but occasionally heavy traffic requirements.
The solution for Fast Ethernet was to reduce the maximum network diameter by approximately a factor of 10 (to a little more than 200 meters).
Increasing the Ethernet transmission rate by a factor of ten over 10Base-T was not a simple task, and the effort resulted in the development of three separate physical layer standards for 100 Mbps over UTP cable: 100Base-TX and 100Base-T4 in 1995, and 100Base-T2 in 1997.

 Fast Ethernet Cable Assemblies: MII, 100Base-T, Fiber Optic, Hydra, Plenum, PVC
Such auto-sensing cards allow workstations to automatically switch to Fast Ethernet (when, for example, the servers and repeaters are upgraded) without the need for a LAN administrator to pop open each PC on the network and reconfigure DIP switches on the adapter card.
Perhaps the simplest is to install a Fast Ethernet adapter in the existing server, alongside the 10-Mbps Ethernet adapter, and use this connection to support a Fast Ethernet repeater and workstations.
The Fast Ethernet standard is designed to provide flexible solutions for a wide variety of cabling situations.
