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!

Life On Campus

Life on Campus

At DCU, our students can expect a unique campus experience. We are known for our excellent teaching and learning facilities, our active clubs and societies, and our great social and sporting facilities. All this makes DCU an exciting place to be. 

DCU has three academic campuses; Glasnevin, St. Patrick’s and All Hallows (both in Drumcondra), all close to Dublin City centre. 

They can be reached by public transport, Dublin Bus and Bus Éireann, with our Drumcondra campuses a ten minute walk from Drumcondra Train Station. Glasnevin is a 20 minute walk from St Patrick’s and All Hallows. They are also linked by Dublin Bus.

Each campus has a library (O’Reilly, Cregan and Woodlock Hall), study spaces, restaurants, and on-campus residencies. There are sports facilities on Glasnevin and St. Patrick’s, and there is a dedicated sports campus, St Claire’s, located near Glasnevin on the Ballymun Road.

DCU’s 19,000 students have access to exceptional teaching and learning facilities across our three academic campuses. 

These include modern learning theatres, research centres, a new media and TV studio, radio/podcast studios, computer suites and advanced labs in the areas of Languages, Engineering, Physics, Chemistry and Biotechnology, as well as a Sports Performance centre and a training hospital ward. In 2021, we opened our first virtual reality ‘Leadership Lab’, which is located in our Business School.

We continue to improve and update our facilities. For example, construction of a new world-class STEM facility is underway on the Glasnevin campus. With capacity for an extra 3,000 STEM students, this facility will advance DCU’s international reputation for excellence in science and health, computing and engineering disciplines.

Studying in DCU isn’t just about course work. The university is rich in student life and activities.

There are more than 140 clubs and societies for students in DCU, with ‘Clubs & Socs’ days taking place on both the Glasnevin and Drumcondra campuses at the start of the academic year. They span everything from rugby to rock climbing, anime to jazz.

For many students, sport is an important part of the DCU experience. DCU’s Sports Complex boasts a 25 metre swimming pool, fitness centre gym, all-weather pitches and squash courts, as well as soccer, GAA and rugby pitches. DCU Dóchas Éireann, the university’s GAA club, is the largest third level Gaelic Games club in the country. Meanwhile, DCU Athletics has been Ireland’s highest achieving university club for many years. And DCU has dozens of other clubs to get involved in, from Archery to Weightlifting. 

The Glasnevin campus is home to our purpose built, state-of-the-art student centre, The U, which serves the needs of a rapidly growing student body. Here, you will find the Student Leadership and Lifeskills Centre, performing arts and cultural spaces for students and the wider community, and the Entrepreneurship and Innovation Hub. Also located on our Glasnevin campus is The Helix, our renowned performing arts centre.

On our St Patrick’s campus, we have the Java Student Hub, a vibrant, warm and welcoming space where students can meet for coffee, play music, use the projector to watch events, or just relax. The walls of the Java Hub were designed based on the cultural history of St Patrick’s Campus, including the special references to the notable sporting history and history of the arts.

We have a number of academic, professional and social supports for students.

Student Advice Centre - Offers a wide range of supports and services to students and advice 

The Writing Centre - drop-in writing workshops for students through the academic year 

Maths Learning Centre - provides maths support for students of all ability levels with maths modules 

Student Learning - facilitate the transition from passive to active learning for students at DCU, by teaching study skills, nurturing critical thinking and building student confidence. 

Careers work with students to help them on their professional journey into graduate employment.

Our student support team offers a comprehensive support programme, helping students make that all important transition into university life and focusing on building confidence and skills which are key to success at third level.

FAQ Icon

What is the difference between Computing for Business and Computer Science?
Computing for Business is about how computers are used in business.  Specifically, this focuses on technology within companies and encompasses all the various types of software, such as database management, relationship management and so on. You will learn to understand how software and information systems address real-world business problems and how you can best use computing technology to help organisations work together.  You will learn how to use and manage information technology and systems to improve and even re-design the way organisations do business. There is some programming on the course but it is a lot less programming than in our Computer Science degree.

Computer Science is our technical Computer Science degree. 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.


What type of jobs would people do after Computing for Business? Is this course half business and half computing?
The B.Sc. in Computing for Business gives you the foundation for a career in IT in modern business enterprise.  You will find opportunities all over the world in banking and finance, high-tech enterprises, the government sector, e-commerce etc. Enterprise Computing students learn about many different aspects of technology and can decide what they would like to when they graduate. Many students are now working as systems analysts, business analysts, technical support, network engineers, web developers and project managers.  They are highly sought after graduates.


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.

Is DCU all one campus?

 DCU is a multi campus university - the Glasnevin, St Patrick's and All Hallows campuses. The St Patrick's campus is where the Education courses are taught and some of the subjects from the BA Joint Honours degree. There is a 20-25 minute walk between the campuses but there are buses and bikes available to go between them also.
