TCP/IP Introduction

Prerequisites:

Course Description:

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.

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 Should Attend?

System Administrators and other staff who are required to understand a TCP/IP Network
