What is a computer science degree? (With skills and careers)
Updated 25 July 2023
As the world relies more on digital technology, experts in this field are becoming even more essential. This makes university courses such as computer science degrees especially valuable, as they educate the next generation of digital pioneers. If you like computers and other types of digital technology, this field of study could be for you. In this article, we explain what a computer science degree is, the importance of pursuing this degree, what the coursework entails and review potential jobs after graduation.
What is a computer science degree?
A computer science degree is the focus of theoretical principles surrounding computation, often combined with scientific theories and their application in real-world environments. It often uses protocols and algorithms to process data. Study courses typically include:
how computer systems work
how to design software
problem-solving using computers
managing databases and data analysis
how to write code
You may typically learn about the hardware that powers computers and various coding languages like C++ and Java. It also teaches you the various concepts within the field and how to use them in different environments. At its core, a computer science degree teaches the systematic acquisition, compilation and analysis of information and data using computing technology and models. Universities typically award computer science degrees as a Bachelor of Science (BSc) at an undergraduate level. However, you can continue your education and pursue a master's or even PhD in computer science.

Advantages of studying computer science
A computer science degree teaches you skills that you can use in a wide variety of jobs. Here are some reasons you may study computer science:
Growing demand: As technology becomes integrated more and more into our everyday lives, the demand for experts in computer science and related fields is increasing quickly.
Career prospects: Owing to the increased need for computer scientists, there are a wide variety of jobs open to you once you graduate, both in computer science and in related fields of work.
Broad curriculum: Because of the varied choice of modules, you're likely to find a role that interests you no matter what area of technology you're passionate about.
How long does it take to get a computer science degree?
How long you'll need to study for your computer science degree depends on whether you study full time or part time. A full-time degree typically takes around three years, and a part-time degree is likely to take between four and five years. Note that this varies between institutions and the specific course of enrolment. Your course may also take longer if you decide to join a work experience scheme for some of your study time.
What modules to study?
The modules that you study vary from institution to institution. You should consider this carefully when deciding where to study. However, some topics are intrinsic to the field of computer science and they are highly likely to be on the curriculum, no matter where you study. These may include:
Internet of things
Later in your studies, such as in your second or third year, you can tailor your course more to your individual interests and career plans. However, there are likely to be certain modules that you must take to fulfil your degree's credit requirements.
What assessments do you complete?
To get your degree, you may demonstrate that you have the skills and understanding of the principal areas of computer science. Universities assess these skills and knowledge throughout the course. Assessments you may complete include:
Coursework: The coursework strand of your computer science degree may consist of written assignments, programming assignments and online quizzes.
Exams: You will need to sit unseen written examinations testing you on a broad selection of topics across a module.
Final project: This is the equivalent of a dissertation and comprises several aspects, including submitting a proposal, doing research and writing your conclusion on the topic.
What skills do you gain?
When studying for a degree in computer science, you may develop both hard and soft skills that are transferable to other roles. Here are examples of those skills that may be helpful in your career:
You're likely to develop a range of soft skills that you could use in a variety of workplaces. Honing these skills can help you be effective in your role and transfer to other roles in the future. Here are skills you may enhance while gaining your degree:
Innovation: A core factor of computer science degrees is using computation models to provide innovative solutions to problems involving data, so you'll develop a strong sense of innovation.
Communication: Across your studies you work both alone and in groups, meaning you develop your written and verbal communication over the years.
Attention to detail: As you work with program and coding systems, attention to detail is a must for any successful computer science graduate.
Critical thinking: You may solve many computational problems throughout your degree, so critical thinking skills are essential.
Alongside these personal skills, you may also develop several technical or hard skills. The technical skills that you learn throughout your computer science degree vary depending on the institution you're studying at. Here are hard skills you may gain:
coding languages like Java, C++, HTML, PHP and Python
database creations and maintenance
AI applications and machine learning
web development and site hosting
operating system design
digital security and cryptography
These skills can help introduce computer scientists to various professions, such as network engineers, data scientists, data analysts, programmers and web developers. Although students often learn to work with more than one coding language, it's common to specialise in just one at first. The technical skills of a computer scientist primarily involve the software aspect of computing, whereas hardware is the primary concern of a computer engineer.
Careers for computer science graduates
Following graduation, there may be several careers available to you in this field. This may include careers both in computer science and in similar fields, such as cybersecurity. Below are several careers suitable for someone with a computer science degree:
