BSc Computer Science
About this course
Computer Science is the rigorous study of computation: the theory and mathematics that underpin it, the systems and software that implement it, and the applications that have transformed every aspect of modern life. It is a discipline that demands both abstract thinking and practical skill, asking you to reason about algorithms, to understand how hardware and software interact, and to design and build systems that are correct, efficient, and maintainable. From the internet and mobile computing to machine learning and cybersecurity, the work of computer scientists shapes the world in ways that extend far beyond the technology sector. At Cardiff University, this three-year full-time programme covers the foundational areas of the discipline with rigour and depth. You will study algorithms and data structures, programming paradigms, computer architecture, operating systems, software engineering, databases, networks, and the theoretical foundations of computation. Programming is taught across multiple languages and you will develop the habit of thinking algorithmically, the ability to decompose problems, design solutions, and reason about their correctness and performance. Cardiff is a Russell Group university and its Computer Science department has a strong research profile, meaning the teaching you receive is informed by active inquiry into the discipline. Practical work is woven throughout the programme, from early exercises in coding and problem-solving to larger group and individual projects later in the degree. You will build confidence in designing, implementing, and evaluating software systems, and you will develop the communication and collaboration skills that are essential in professional computing roles. Graduates enter careers in software engineering, systems development, data science, cybersecurity, research, and technology management. The breadth of the computer science labour market means that graduates are recruited across virtually every sector of the economy. Many go on to postgraduate study, whether in specialist computing areas or in research degrees that extend the work begun at undergraduate level.
