It also covers modulation techniques and modems - their function and operation, features and the need for standards. Protocols Aims to provide an understanding of the rules to be applied to ensure efficient and reliable data communication between devices. Networks 1 Gives and introduction to networking. It explains why networks are used and what they are used for. The varying types of network - LAN, MAN and WAN are introduced.
Emphasis is placed on packet switching on WANs.
Networks 2 Gives an introduction to Local Area Networks and associated IEEE802 standards. Ethernet and Token Ring networks are dealt with along with internetworking devices. LAN protocols are explained with reference to the OSI model and also higher level protocols, needed for internetworking, are introduced. This module is developed around a central, simulated Conceptual Design exercise. This exercise represents the core of the work to be undertaken by the user in the module.
