Page 10: Chapter 1: Product Overview
Chapter 1: Product Overview Introduction to Fast Ethernet Standard 10 Mbits/s 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 Mbits/s Ethernet has become a serious bottleneck. -
