English Language Requirements

If English is not your first language you will need to provide evidence of your English language proficiency as detailed on our website. Applicants for this course should have a minimum IELTS (Academic Version) English Proficiency of 6 overall (or equivalent) with nothing less than 6 in each component.

Computer Science (Infrastructure) is about developing software and infrastructure for applications ranging from those on smart devices to those in global corporations. This course provides the skills required to build data centres and networks, and to develop software securely, individually and in teams.

Recent graduates work as software developers, software engineers and system administrators. No prior programming experience is required.

Application areas include intelligent cities, ethical hacking, search-engine development, games, and legal and financial software.

You’ll gain a working knowledge of the components of a computer and a network, become familiar with the components of an operating system, and learn to administrate large distributed systems. You’ll write programs in multiple languages for platforms varying from single-user, single-platform applications to multi-user, multi-layered distributed systems.

You’ll learn how to ensure that an IT infrastructure complies with the most effective security techniques; learn many technologies, about web clients and servers, data storage, manipulation and analysis, the use of different platforms and physical devices, and techniques for developing systems, from small mobile devices to cloud-based services. You’ll learn how to integrate these technologies.

You’ll also study the architecture and infrastructure of large systems; how to design, document, implement and manage them.

In your final year, you’ll present your work at a highly regarded project fair to an audience of industry partners and experts.

Study Abroad Opportunities

You can apply to participate in an international exchange for the second half of third year as part of your experiential learning. Erasmus places are available in a number of European countries and there are also other student exchanges in countries such as South Korea. All modules taken abroad are taught through English.

Work Placement

You can apply for work placement in Year 3, to gain invaluable experience in the IT industry, or you can study further modules.

Professional Accreditation

Students earning BSc (Hons) will be eligible for Professional Membership of BCS, the Chartered Institute for IT (MBCS).

Graduates are working as Software Engineers, Software Developers, Systems Administrators, Virtualisation Engineers, IT Security experts and Database Administrators in global organisations such as IBM, Amazon and Oracle, local successful companies such as Ocuco, Version 1 and Digital Planet, and in start-ups.
Many also work in IT departments of banks, building societies and government organisations or as software or infrastructure consultants.

Having worked as a computer technician for a couple of years, I was made redundant and found I was being overlooked for jobs because of my lack of formal qualifications. I found the diversity of subjects and the pace of the course suited me very well. As part of the course I worked as an intern for the company with which I now work full-time. The course continued to be challenging and interesting throughout, and has given me a career path I would have never achieved on experience alone.

Graduates are qualified to pursue postgraduate studies to MSc, MPhil or PhD levels.
