Before we dive into the complex worlds of networking devices, the TCP/IP and DoD models, IP addressing, subnetting, and routing in the upcoming chapters, you have to understand the big picture of LANs and learn the answer to these key questions: How is Ethernet used in today’s networks? What are Media Access Control (MAC) addresses, and how are these identifiers utilized in networking?
This chapter will answer those questions and more. I’ll not only discuss the basics of Ethernet and the way MAC addresses are used on an Ethernet...
