COMP2207 Distributed Systems and Networks

Module Overview

The networking aspect of this module will expose students to the principles of layered communication protocols, the architecture of the Internet, and the principles of how the components of the TCP/IP layered model are designed and operate. The distributed systems aspect will focus on distributed algorithms, but include distributed communication, distributed objects, web interfaces and peer-to-peer systems. Students should gain a clear understanding of the technologies covered in terms of the underlying fundamental principles. Hands-on experience is also gained through the coursework.
