TCP/IP Networking

0800 1337 401

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.

Prerequisites

Understanding of an operating system is essential.

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.
