Introduction

In the first week, the students should also be introduced to the local network, and be given login's, as well as being shown how to access the Internet. The first Practical Worksheet should be completed over a period of two weeks, and is intended to be a gentle introduction to the WWW, and its search facilities. An on-line version is also available from the cnds@napier WWW site.

ping

This worksheet gives a basic introduction to the concept of ping, which is one of the most widely used techniques for testing a network connection. Various WWW sites around the Internet have been chosen. These can be changed, depending on the situation. NOTE: This worksheet can be customized for the required setup, the main principle is to show how ping is used to sense if a host is operating, and to give a basic measure of the time that data packets take to reach a destination.

traceroute

This worksheet outlines some of the main concepts in determing the route to a remote note (using traceroute). As with ping, this is used extensively to test a network when there is a fault. NOTE: This worksheet can be customized for the required setup.

IPConfig

This worksheet gives a basic introduction to how a user can determine the basic setup of their host (using WINIPCFG or IPCONFIG). NOTE: This worksheet can be customized for the required setup.

WinSock programming

TCP/IP is the foundation of the Internet, and this worksheet is intended to show how programs react to received data packets, and how they are sent from a host.

 

WinSock client-server

This worksheet enhances the previous worksheet to show how client-server applications can be developed.
