Unit 8

Lesson 2 - Expanding the Small Network

   Introduction

As a network grows, it is usually necessary to provide additional options and services for both network users and administrators. As with most network issues, both software and hardware are generally required when a small network graduates to become a larger LAN.

A peer-to-peer network usually upgrades to a full client/server network operating system (NOS) when the network needs specialized servers. A full NOS is also necessary as the number of users grows, and administrators want finer control over user access rights.

Also, a steady increase in user traffic will eventually degrade network performance, just as too many cars on a highway create traffic jams. Thus, when a network grows beyond a certain point, a network administrator usually adds devices to segment the network and isolate traffic within workgroups. This lesson discusses both of these issues, which are common when a network outgrows its peer-to-peer architecture.

   Objectives

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

1.

Name and describe the most common types of dedicated network servers

2.

Explain why the function of a server should determine its position in a traffic isolation plan

Key Point
When a peer-to-peer network grows, it often requires dedicated servers and a client/server NOS.
