Title: Module 7 Introduction
Course: CNT 2001 Computer Networks & Communications > Section: Module 7 LAN Technologies

Introduction

We will expand upon our exploration of LANs (local area networks). We will introduce Ethernet as the dominant LAN technology on the OSI Data Link layer. We will expand on the physical installation of wireless LAN technologies. And, we will explore the physical design of a small office / home office (SOHO) network.

Learning Objectives:

- Explain what CSMA/CD is and how it works.
- Explain what CSMA/CA is and how it differs from CSMA/CD.
- Explain how a broadcast is used to transfer data around a network.
- Explain what collisions are.
- Explain how collision domains are broken up.
- Explain what network speed is.
- Explain how distance applies in networking and how it can affect the design of a network.
