1. Introduction

Specification point:

iv) Describe, using diagrams or otherwise, the ring, bus and star network topologies


Once you have decided to network a number of computers together, the next decision which needs to be made is which network layout or topology would be the best to use.

There are a number of different topologies to choose from, the three most popular being bus, ring and star.

Read through the next few pages to find out about these three different network layouts. You must be able to describe the differences between them, to identify the advantages and disadvantages of each and if possible, provide a drawing to illustrate your written points.
