The purpose of the networking guidelines are as follows:
to assist students in understanding the benefits of networking
to help students place in context their current stage of networking
development in their school.
to assist students in planning the next stage of network development
in their school.
to provide standard networking ‘models’ and best practice to students
that will assist students in their network planning.
This document includes information under the following main headings:
Introduction to Networking
Advantages of Networking
Types of Networks
Models of networking appropriate to students
NCTE recommendation to students
Some relevant terms.
1.1. Basic of Networking
A computer network consists of a collection of computers, printers and other
equipment that is connected together so that they can communicate with
each other. Fig 1 gives an example of a network in a school comprising of a
local area network or LAN connecting computers with each other, the
internet, and various servers.

Broadly speaking, there are two types of network configuration, peer-to-peer
networks and client/server networks.
Peer-to-peer networks are more commonly implemented where less then
ten computers are involved and where strict security is not necessary. All
computers have the same status, hence the term 'peer', and they
communicate with each other on an equal footing. Files, such as word
processing or spreadsheet documents, can be shared across the network and
all the computers on the network can share devices, such as printers or
scanners, which are connected to any one computer.

Client/server networks are more suitable for larger networks. A central
computer, or 'server', acts as the storage location for files and applications
shared on the network. Usually the server is a higher than average
