Making Computer Networks Work For You


Course Contents:

Lecture 1 Types and Uses of Computer Networks
Lecture 2 - Component Parts of Protocols
Lecture 3 - Planning for the creation of a Computer Network
Lecture 4 - The TCP/IP Protocol for Computer Networks



Summary

This lecture covers the basic concepts of various types and uses of Computer Networks. The implications and uses of Networks in Business and Science are covered in detail.
By the end of the lecture you will be able to understand jargon and appreciate the advantages, constrains and uses of computer networks in various settings.
Computer Networks allow the sharing of resources, data and hardware, in an efficient way. Intra and Extranets are powerful business tools for all sizes of companies, but the careful assessment of needs and solutions before taking the plunge is essential.

    Lecture 2 - Component Parts of Protocols

    Summary

    This lecture covers how the functionality of a computer network can be broken down into manageable chunks using a layer model. The approach of describing the operation of a computer network in this way is similar to the Object Orientation of Software.
    By the end of the lecture you will be familiar with the computer network layer model and the functionality described by each layer. This background knowledge is helpful when analysing Computer Networks.
    The functionality of Computer Networks can be described by a layer model, that breaks down the various design aspects into manageable chunks. This is instrumental in analysing and improving the design of Network Protocols.

    Lecture 3 - Planning for the creation of a Computer Network

    Summary

    This lecture covers all platform independent issues related to the creation of a computer network. It builds a knowledge base that can easily be used to make informed decisions. The material covered here is also intended to help with ongoing maintenance of networks.
    By the end of the lecture you will be able to adapt the network type and architecture to your needs. You will also be able to plan for procedures and hardware required for auditing, disaster recovery and resource sharing.
    It is crucially important to assess the intended use of a computer network thoroughly before going out to buy the component parts. Cost and use of various components varies greatly, so does the cost of upgrading. Knowing about the component parts of computer networks also enables you to assess and administer an existing computer network.

    Lecture 4 - The TCP/IP Protocol for Computer Networks

    Summary

    TCP/IP is a de facto standard protocol used in computer networks throughout the world. It is one of the most robust and flexible protocols available. This lecture covers material which forms the basis of understanding TCP/IP ranging from Acronyms, Addressing to Troubleshooting.
    By the end of the lecture you will be familiar with the main concepts of TCP/IP. The knowledge acquired is generally valid, whether you are dealing with a Windows NT or a UNIX installation. The knowledge acquired here forms a solid basis on which more operating system specific courses can be taken.
    TCP/IP is not as frightening as it sounds. The principles are generic and given a systematic approach to the material anyone can master them. Due to the generic nature of the protocol the material is invaluable to anybody with an interest in Computer Networks.
