What is computer science?

Computer science focuses on the study of algorithms, data and the overall functioning of computers. It’s anIT field that explores how information is processed, stored and shared.

Within computer science, there are many different career paths. You may choose to go into the research side or you might specialise in artificial intelligence, developing computer models that can learn and adapt. You could focus on cybersecurity and protecting information from malicious attacks, ensuring data is kept safe.

What is software engineering?

Software engineering focuses on the design, development and maintenance of software applications. Students can develop plenty of practical skills, including coding, bug fixing, content design, and project management, and learn a range of different software development methodologies .

Software engineers often work in teams, bringing together different perspectives to solve complex problems.Good communication andteamwork are important, as engineers must coordinate with colleagues, stakeholders and clients to deliver projects.

Differences between software engineering and computer science

While bothcomputer science and software engineeringfall under the 'tech' umbrella, they are very different careers.

Computer science goes into the ‘why’ and ‘how’ of computer processes, with the aim of advancingthe boundaries of what technology can achieve.

On the other hand, software engineering focuses on creating and maintaining software systems. It takes the theory of computer science and applies it to designing, developing and maintaining practical software solutions.
