Introduction to Fast Ethernet

Standard 10 Mbps Ethernet has served well for past generations of 286 and

386 machines performing simple file transfers. However, with the inevitable growth in corporate network size and the introduction of fully-functional 32-bit PC architectures, and operating systems running complex applications, 10 Mbps Ethernet has become a serious bottleneck.

With the recent flood of choices for upgrading media bandwidth, 100 Mbps Fast Ethernet has become the most popular choice because of its low cost, compatibility with existing Ethernet applications, and the fact that it can run on top of an installed base of twisted-pair cabling. Fast Ethernet can be easily integrated into an existing 10 Mbps Ethernet environment with no need for protocol translation or changes to network software.
