WHAT IS ETHERNET?WHAT IS ETHERNET?

•ETHERNET history– developed in 1973 as shared medium– bandwidth 10 Mbps– bus topology– CSMA/CD procedure for media access

•ETHERNET today– scalable bandwidth with 10/100/1000

Mbps– switched “Full Duplex” connection

without collisions– IEEE standards for prioritization and flow

control– standards for Copper, Fiber, Plastic, and

Wireless transmission
