The aim of this module is to build on the foundations of data and information systems laid down in the first year, learn how to design and manage fully structured data repositories and explore the rather different principles and techniques involved in representing, organising and displaying unstructured information.

This module is designed to provide an introduction to the statistical principles used in data science and their applications, and the use of practical programming packages for data analysis and visualisation. You will also study data analysis techniques, including causal inference, correlation, classification, regression, and clustering.

The aim of this module is to provide an understanding of the principles that underlie the design of web applications, and to provide practical experience of the technologies used in their construction.

Artificial intelligence will be a great driver of change in the coming decades. This module provides an introduction to three fundamental areas of artificial intelligence: search, knowledge representation, and machine learning. These underpin all more advanced areas of artificial intelligence and are of central importance to related fields such as computer games and robotics. Within each area, a range of methodologies and techniques are presented, with emphasis being placed on understanding their strengths and weaknesses and hence on assessing which is most suited to a particular task.

The aim of this module is to provide an introduction to the C++ programming language. The contents covered by this module include basic concepts and features of C++ programming (e.g., operator overloading), C++ Standard Template Library, and inheritance, function overriding and exceptions.

A bare computer is just a complex pile of electronics. What a programmer needs is much higher-level: a human-usable interface; a file system; communication with other computers. The system should be able to share itself between many users, but stop them from interfering with each other's work. It should be secure. In short, what a bare computer needs is an operating system. This module studies the functionality an operating system must provide, and the principles of how that is done.

Want to configure Internet routing protocols for interconnecting networks? Or configure Ethernet switches and associated protocols? Build on your understanding of Internet routing protocols, Ethernet and other IP networking. Gain practical experience of configuration. Design addressing structures and interconnecting strategies for campus scale networks.

This module introduces a number of ideas of computer security, ranging from ciphers to malicious software. After completing this module a student will be able to make a sufficiently informed judgement on most computer security issues and computer security solutions. The module includes programming coursework encouraging the students to experiment with ideas of computer security on simplified examples.
