How Do Networks Work
A 2-day hands-on course
Practically all computers are now networked, either in Local Area Networks, Wide Area Networks or via the Internet. Networks are complicated. This is partly due to the fact that a network is often made up of multiple sections, involving the interaction of software and hardware from different suppliers. However once you understand the basics you have a solid foundation on which to build. This hands-on course provides those basics, in a jargon free way; and because you will actually build a complete working network you will really understand how it works.

Who should attend
The course is aimed at those using networked PCs (or about to do so) and who need a better understanding of network concepts and jargon, a real understanding of the network components (which will be achieved in the hands-on sessions) and an appreciation of the bigger picture, encompassing the workstation, the server and other networks. The course will also benefit those planning to become more involved in the technical issues and day-to-day network troubleshooting.

 Hands-on
  ·   Install and test the network interface card 
  ·   Cable up the network
  ·   Test the network 
  ·   Select and Install the client
  ·   Select and install the protocol
  ·   Use the network
  ·   Install TCP/IP
  ·   Join an Windows 2000 domain
  ·   Use network monitoring tools

Case Study
During the course a case study based on a recent project will be considered. This will give participants a chance to review a real-life specification and proposed solution.
