Introduction

We have already explored a variety of LAN technologies. Now it is time to explore Ethernet in depth. Ethernet is by far the foundation technology that is in use on most wired LANs today. Early in the evolution of LANs there were other LAN technologies that might have been implemented. But today, Ethernet is in such widespread use that it is simply expected that LANs will run over Ethernet. When a consumer goes to a retailer and selects components to build into a wired LAN for personal use, those components are going to be designed to operate over Ethernet. The great advantage of this ubiquity of Ethernet is that there is now general interoperability of LAN equipment that is based on Ethernet.

Learning Objectives:

- Discuss why Ethernet is the most commonly used LAN technology.
- Discuss the implementation of CMSA/CD in Ethernet.
- Describe various cable-based Ethernet technologies.
- Compare baseband Ethernet to broadband Ethernet.
- List some common Ethernet technologies such as 10Base-T, 100Base-T, 1000Base-T and 10 Gigabit.
