IT vs Computer Science – What’s the difference?

Computer Science (CS) and Information Technology (IT) both deal with computers, but they focus on different things:

• Information Technology is all about the technical side – how computers work and how to make them do amazing things. CS deals with developing, implementing, supporting, and managing computers and information systems, even things like AI and machine learning.
• Information Technology is more about using and managing technology in real-world settings. IT pros work with networks, databases, and systems to keep everything running smoothly for a business or organisation. IT involves working both with hardware (e.g. CPUs, RAM, hard-disks) and software (e.g. operating systems, web browsers, mobile applications).

Students often assume that Computer Science, Software Engineering, and Information Systems are the same. But as Associate Professor Walayat Hussain, from Australian Catholic University explains, each has its own focus and purpose:

Students often consider computer science, software engineering, and information systems as similar fields, alongside general IT programs. However, there are differences. Computer science is more theoretical, involving algorithms, computation, and mathematics. If a student wants to design a new programming language, computer science is a good option. When I started my computer science studies, we did mathematics like calculus, building algorithms. For example, during my undergraduate studies, I developed a Tetris game, which involved pixel calculations and mathematics—this falls under computer science.

Associate Professor Walayat Hussain

According to Professor Walayat, software engineering applies engineering principles to software development, focusing on building large, reliable software systems and managing software life cycles using methodologies like Agile.

Information systems, or business information systems, are more general, dealing with databases and project management, aligning technology with business management.

General IT covers a bit of everything, including programming, networking, database, and web development.

IT vs Computer Science specialisations
