CS381 Outcomes
• By the end of the module you should be able to:
– understand the concept of clients and servers and examine technologies
used to support distributed applications.
– understand the architectural and programming paradigms used in
distributed system development, and how middleware components
mediate between clients and servers.
– categorise and evaluate these tools according to different criteria such as
applicability and ease of use, and intelligently participate in the selection
of appropriate tools and architectures, or combination, to solve simple
web-related problems.
– use the presented technologies in practice to develop distributed
applications.
