Objectives

 Identify the basic characteristics of network media used in

Ethernet.

 Describe the physical and data link features of Ethernet.

 Describe the function and characteristics of the media access

control method used by Ethernet protocol.

 Explain the importance of Layer addressing used for data

transmission and determine how the different types of addressing impacts network operation and performance.
