1.1 The Ethernet System

This chapter provides a brief tutorial on the Ethernet system. We'll begin with the origins of Ethernet and the Ethernet standards, and then describe the essential features of Ethernet operation.

Ethernet is a local area network (LAN)*1 technology that transmits information between computers at speeds of 10 and 100 million bits per second (Mbps). Currently the most widely used version of Ethernet technology is the 10-Mbps twisted-pair variety.

The 10-Mbps Ethernet media varieties include the original thick coaxial system, as well as thin coaxial, twisted-pair, and fiber optic systems. The most recent Ethernet standard defines the new 100-Mbps Fast Ethernet system which operates over twisted-pair and fiber optic media.
