Topic 2: Architecture
Description
In this topic, we consider the concepts of Network and Software Architecture.We look at how network architectures are usually defined and viewed, and use the Internet as a specific example of the views. We also explore the field of software architecture and what is necessary to be able to define the architecture of a piece of software. We explore the various frameworks that exists to describe software architectures. We concentrate on using UML as a method of describing software, and look at World-Wide-Web technologies as examples of software architectures.
