General description
This module introduces the methods and technology used in modern computer based communications systems. It covers the basic concepts and terminology of point to point and broadcast communications over both public and private networks. Ethernet is studied in detail as an example of a local area network. Some background information is provided on the history and development of public telephony. The nature and potential of telematics applications and the component technologies are discussed, as are the characteristics of new high speed technologies.

The purpose of this module is to introduce the problems encountered and the methods used in modern computer-based communications and to provide an insight into the nature and potential of telematic applications.

Learning outcomes
On successful completion of the module, students will understand:

The needs for standards and the areas they cover. The standards setting process and the standards setting bodies - including BSI, ISO, ANSI, IEEE, ITU and IAB. Local and organisational standards and their relationship to national and international standards. The ISO Model. The weakness of standards and the standard setting process. De facto standards.
