Fast Ethernet Technology
The growing importance of LANs and the increasing complexity of desktop computing applications are fueling the need for high performance
networks.100BASE-TX(FastEthernet) providesacost-eectiveandhigh-performancesolutionforsmallworkgroups,SMBs(SmalltoMedium
Businesses), and any network supporting bandwidth-intensive applications. Fast Ethernet technology operates at 10 times the speed of traditional
Ethernet,oeringmaximumperformanceandenhancedcapabilityforexistingEthernet-basednetworks.
100Mbps Fast Ethernet is a standard specied by the IEEE 802.3 LAN committee. It is an extension of the 10Mbps Ethernet standard with the
ability to transmit and receive data at 100Mbps, while maintaining the CSMA/CD Ethernet protocol. Since the 100Mbps Fast Ethernet is compatible
with all other 10Mbps Ethernet environments, it provides a straightforward upgrade and takes advantage of the existing investment in hardware,
software, and personnel training.
Gigabit Ethernet Technology
Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet structure, format, and support for CSMA/CD protocol, full duplex,
ow control, and management objects, but with a tenfold increase in theoretical throughput over 100Mbps Fast Ethernet and a one hundred-
fold increase over 10Mbps Ethernet. Since it is compatible with all 10Mbps and 100Mbps Ethernet environments, Gigabit Ethernet provides a
straightforward upgrade without wasting a company’s existing investment in hardware, software, and trained personnel.

as computers and their busses get faster and more users use applications that generate more trac. Upgrading key components, such as your
backbone and servers to Gigabit Ethernet can greatly improve network response times as well as signicantly speed up the trac between your
subnetworks.
Gigabit Ethernet enables fast optical ber connections to support video conferencing, complex imaging, and similar data-intensive applications.
Likewise, since data transfers occur 10 times faster than Fast Ethernet, servers outtted with Gigabit Ethernet NIC’s are able to perform 10 times the
numberofoperationsinthesameamountoftime.Inaddition,thephenomenalbandwidthdeliveredbyGigabitEthernetisthemostcost-eective
