Frequently Asked Questions about Computer Science

Computer science is a field of study that explores computing systems and technology. It involves the examination of software, hardware, the internet, and programming languages. The discipline combines aspects of mathematics and engineering to model, design, and test algorithms, which are step-by-step descriptions of how to accomplish tasks.

Computer science is about the study and application of computing technologies and methodologies. It involves understanding the design, application, and usage of computer systems, software, and networks. Areas of focus include programming, algorithms, data structures, artificial intelligence, and network architecture. Practically, it is the underpinning for virtually all modern technology applications like web browsing, video gaming and even digital financial systems.

An algorithm in computer science is a set of specific, step-by-step instructions or rules to be followed in calculations or problem-solving operations, especially by a computer. It is like a recipe that describes the exact steps required for the computer to solve a problem or reach a goal. These can range from simple processes, such as organising a list of numbers, to more complex procedures like image recognition and machine learning. Algorithms are fundamental to computer programming and software development.

With a Computer Science degree, you can work in a wide range of sectors such as software development, data analysis, cyber security, game design, IT consultancy, and website development. It also opens up opportunities for research-based roles in academia or private sectors.
