The main objective of this course is to provide delegates with a basic understanding of computer network technologies and concepts. It will begin with an overview of different network types and how these fit together within Janet. It then moves on to consider different network models and how they can be applied. The course will then look at some of the physical aspects of networks and the protocols that make it all work. Finally after a review of basic network applications, delegates will be lead through a very practical review of some of the key issues associated with campus networking.
