Computer Networks (G5115)

15 credits, Level 5

Spring teaching

This module provides an introduction to the basics of packet switching technologies as used in the internet. Emphasis is placed on core Internet protocols such as IP and TCP.

Subjects covered include:

  • network access technologies
  • design of network protocols using layering
  • local area networks
  • TCP/IP routing and switching
  • and congestion control.

This module introduces the internet with a top-down view: the accent is on layer abstractions and the associated protocols (and how to program with them). Particular attention is paid to questions of network security.

Contact hours and workload

This module is approximately 150 hours of work. This breaks down into about 33 hours of contact time and about 117 hours of independent study. The University may make minor variations to the contact hours for operational reasons, including timetabling requirements.

We regularly review our modules to incorporate student feedback, staff expertise, as well as the latest research and teaching methodology. We’re planning to run these modules in the academic year 2024/25. However, there may be changes to these modules in response to feedback, staff availability, student demand or updates to our curriculum. We’ll make sure to let you know of any material changes to modules at the earliest opportunity.
