Lesson 1 - Network Classifications and Topologies

   Introduction

Two of the most important characteristics of a network are size and shape. Both of these factors influence the transmission technologies and communication protocols that the network uses. This lesson reviews the terms and concepts that network professionals use to describe the broadest, most fundamental aspects of a network's design.

At the end of this lesson you should be able to:

1.	Name and describe the major classifications of computer networks
2.	Explain the factors that distinguish the major network classifications
