TCP/IP Networking Course Overview

The TCP/IP Networking course introduces the delegate to the main concepts of TCP/IP. It describes the structure of the TCP/IP Protocol suite and the functions and Protocols at each layer.

Skills Gained

At the end of the course the delegate will be able to:

• Describe the four layers of the TCP/IP Protocol suite and the functions of each layer
• Identify the needs of, and the purpose of each of the protocols at each layer
• Use and configure each of the common applications used with TCP/IP
• Set up and configure a small network
• Configure a router using static routing and RIP
• Split a network into three subnets
• Use the common network commands to troubleshoot a TCP/IP Network
• Examine a TCP/IP trace at all levels, and diagnose network problems

Who will the Course Benefit?

Anyone who needs to design and implement a small TCP/IP Network.  The TCP/IP Networking course is also suitable for delegates who need an understanding of TCP/IP and are required to maintain a network.

There are no formal pre-requisites, although knowledge and understanding of UNIX is advantageous, as the course is built around TCP/IP and UNIX.

Course Objectives

To provide the skills necessary for the delegate to design, build and test a small TCP/IP Network, comprising of three subnetworks and two routers. The delegate will learn how to trace and rectify faults on the network.

Requirements

Understanding of an operating system is essential.
