Learning Outcomes

On successful completion of this module students should be able to:

1. demonstrate knowledge of basic Internet and communications concepts.

2. analyse existing distributed systems in terms of architectures and reference frameworks.

3. produce an outline design for a distributed system.

4. demonstrate knowledge of a range of critical issues associated with the design of telematic applications.

5. describe a range of contrasting facilities for the design and construction of distributed applications and assess their relative applicability to real world problems.

6. use a multi-media programming interface and identify the critical issues in specific multi-media applications.

7. build a distributed application using technologies presented during the module.


This module replaces the MSc modules COM5610 and COM5010. We are merging modules into 20-credit blocks to improve coherence across related material. We are also trying to harmonize the home schemes with those taught overseas. The module forms an essential part of the proposed new Internet and Distributed Systems (Advanced) MSc. It will also form part of the conversion MSC in Computer Science.

Brief description

An introduction to communications concepts. An overview of major distribution architectures and frameworks. Design and construction of multi-tier Internet applications. Developing multi-media applications. Java APIs for Internet protocols. Java communication protocols. The Java security model. Introduction to server-side software development.
