INTRODUCTION 
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-T (Fast Ethernet) provides a cost-
effective 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, offering 
maximum performance and enhanced capability for existing 
Ethernet-based networks. 
100Mbps Fast Ethernet is a standard specified 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 path and takes 
advantage of the existing investment in hardware, software, and 
personnel training. 
 
Switching Technology 
Switching is a cost-effective way of increasing the total network 
capacity available to users on a LAN. If an Ethernet network begins 
to display symptoms of congestion, low throughput, slow response 
times, and high rates of collision, installing a switch to a network 
can preserve much or all of the existing network's cabling and 
workstation interface card infrastructure, while still greatly 
enhancing the throughput for users. A switch is a viable solution 
even if demanding applications, such as multimedia production and 
video conferencing, are on the horizon. The most promising 
techniques, as well as the best return on investment, could well 
consist of installing the right mixture of Ethernet switches.
