Aims

This module is intended to provide an understanding of the technical issues involved in the design, analysis and evaluation of modern distributed systems and algorithms. Besides conveying the central principles involved in designing distributed systems, this module also aims to introduce the students to the main principles of distributed computing and of algorithms for distributed tasks.


Learning Outcomes

(LO1) An appreciation of the main principles underlying distributed systems: processes, communication, naming, synchronisation, consistency, fault tolerance, and security.

(LO2) Familiarity with some of the main paradigms in distributed systems: object-based systems, file systems, and coordination-based systems.

(LO3) Knowledge and understanding of the essential facts, concepts, principles and theories relating to Computer Science in general, and Distributed Computing in particular.

(LO4) A sound knowledge of the criteria and mechanisms whereby traditional and distributed systems can be critically evaluated and analysed to determine the extent to which they meet the criteria defined for their current and future development.

(LO5) An in depth understanding of the appropriate theory, practices, languages and tools that may be deployed for the specification, design, implementation and evaluation of both traditional and Internet related distributed computer systems.

(S1) Numeracy/computational skills - Problem solving
