Our world runs on computing. It’s used in every single sector and industry. From climate modelling and the study of disease to high tech companies and the latest online games, innovation and progress needs software engineers to solve problems and build products.


Overview Icon

If you want to know how computers work and learn how to develop cutting-edge computer, internet and mobile technology, choose Computer Science. Along with programming, you’ll study advanced data tools and algorithms, databases, networks and cryptography, along with other much needed skills such as critical thinking and communications skills.

Use the latest real world tools
At DCU, our Computer Science course has a strong emphasis on software engineering, which is writing, modifying and maintaining software systems. You’ll get to study DevOps and full stack development in second year and use Git for all your project work – these hands-on, practical approaches based on the latest industrial practices.

In third year, you’ll go on a six-month work placement at a tech company and you have the option to study abroad too. There is huge demand for graduate software engineers and systems analysts, so you’ll find a world of opportunity awaits once you finish this course!

FAQ Icon

What is the difference between Computer Science and Computing for Business?

Computer Science focuses directly on programming and software engineering. By studying this course you will qualify as a strong programmer and software engineer. This course will give you in-depth knowledge of software engineering and the practical skills to apply this knowledge to develop the technology behind computer games, mobile phones, the Internet, web applications etc. With this degree you can travel the World and work in any country as programming languages are the same Worldwide.

Computing for Business focuses more on the management of technology. For example, perhaps you see yourself in a career in IT Management, Technology Management, or Project Management for a Tech/IT company. This course focuses on the business and management aspects of the computing industry. While this course does have programming modules, it is not the same level of programming as Computer Science.


Is Computers Science (DC121) very design focused?
Computer Science is more programming and software engineering focused rather than design focused. You do not require any past experience in CAD or programming, as all first year modules are taught at an introductory level. If you are someone who wants to have a career in game development, programming is a crucial requirement to have and Computer Science focuses heavily on programming.


Do I need to know how to programme before entering this course?

Students do not require any past programming experience, as all first-year modules are taught at an introductory level. During our courses, you’ll learn coding and programming, and get to grips with databases, operating systems and networks. HTML, CSS, CSS3, Python and Javascript are examples of programming languages taught throughout the course. 


I am interested in studying in Computer Science and was wondering if the course has a work placement module?

All of the courses in the School of Computing (Computer Science, Computing for Business and Data Science) have a paid work placement. Our students go on work placements for a minimum of 6 months in third year. 

The School of Computing students liaise with the DCU INTRA office to organise a suitable placement that is relevant to their programme of study. In the past, many students have been hired by their work placement companies post-graduation. It is a wonderful learning experience and gives students the opportunity to put their learning into practice.
