Computer Science vs Software Engineering
Are you wondering what sets computer science and software engineering apart?
While both degrees require a strong foundation in computer knowledge and problem-solving, software engineering is more specific. It’s about creating and maintaining everyday programs. By comparison, computer science offers a more diverse experience.
Computer science is the study of computers and algorithms, involving theory, design, and the development of anything that can be done on a computer. Software engineering, on the other hand, focuses on designing, creating, and maintaining computer software.
Distinguishing between computer science and software engineering can be challenging if you’re unfamiliar with the terminology, or how various aspects of computer science relate to one another. Both degrees provide a foundation in computer knowledge.
While software engineering focuses specifically on designing and maintaining everyday programs, a computer science degree offers a broader range of skills. The question of whether it is better to be a specialist or generalist doesn’t have a definitive answer. But we can clarify the differences between the two fields.
Difference Between Computer Science and Software Engineering
The differences between the two fields are evident in their differing roles in the broad area of technology research, development, and management. Software engineers use specialized knowledge to develop and maintain computer programs. Computer scientists take a more broad-based approach, using programming, algorithm and security expertise to push the boundaries of technology innovation.
| What computer science is | What software engineering is |
| Computer science is the study of computers and algorithms. The field covers the theory, design, and development of computer systems and technology, including algorithms, programming languages, and software development. It also encompasses areas such as artificial intelligence, computer graphics, and cybersecurity. | Software engineering is designing, creating, testing and maintaining software. Engineering approaches are used to develop software, such as the steps of making specifications, design, coding, testing, and maintenance. Software engineers use knowledge of programming, algorithms, and computer systems to create software that meets user needs. |
The work of software engineers reflects that this is a specialized field focusing on the design, development, and maintenance of software systems. There is an emphasis on practical solutions to real-world problems. What computer scientists do is broader and harder to pin down.
| Job of a computer scientist | Job of a software engineer |
| A computer scientist studies the theory and application of computers and computational systems. They use knowledge of computer science to design and develop software, algorithms, and systems for varied applications, such as artificial intelligence, machine learning, computer graphics, and databases. They also do research and analyze data to drive innovation and advancements. Some computer scientists work in academia, teaching computer science at college or university level. | A software engineer designs, develops, and maintains computer software, using programming languages and tools. They may work on different software applications and systems, such as operating systems, databases, and mobile applications. They also ensure the software is developed efficiently, effectively and is of high quality. Software engineers often work closely with other engineers and stakeholders to understand requirements, and implement solutions to meet them. |
Is Software Engineering Easier than Computer Science?
Software engineering is not inherently more difficult or easier than computer science. You could say they’re about the same. With coursework, it really depends on how hard instructors make the content. In terms of jobs, each competent professional should be able to find a niche that suits their talents and ability level.
Hardest parts of computer science
Some of the biggest challenges in the field of computer science are:
- Understanding and applying complex mathematical concepts, such as algorithms and data structures
- Keeping up with the rapidly evolving technology and advancements in the field
- Developing a strong foundation in programming and computer systems.
Hardest parts of software engineering
In software engineering, you may find these aspects most difficult:
- Understanding and applying software design patterns and principles
- Managing and coordinating large and complex software projects
- Keeping up with the latest tools, technologies, and programming languages used in the industry.

Which Pays More: Computer Science or Software Engineering?
The pay for computer scientists and software engineers can vary depending on factors such as location, experience, and specific job role. Generally, computer science and software engineering are considered high-paying fields, although average pay differs by job title.
| Role | Average base pay (USD/yr) | Average additional pay (USD/yr) |
| Computer science salary | $146,000 | $44,000 |
| Software engineering salary | $117,000 | $34,000 |

Salary figures compare job titles, not degree outcomes. A computer science graduate working as a software engineer would fall into the software engineering category.
Note that pay depends on the specific industry in which one is working, with some industries paying higher than others.
Which One Is Better?
As a career, software engineering offers a much larger employment market than computer science research. Many computer science graduates work in software development rather than in roles titled computer scientist.
Computer science can be considered a broad academic field that contains many occupational disciplines. Computer science graduates can have careers such as computer systems analyst, data scientist, computer network architect, database administrator, cyber security analyst, and software engineer. Computer science research roles typically require postgraduate study.
By choosing a software engineering degree, you’re concentrating on designing, building and maintaining software. AI tools can generate code and suggest fixes, but you still need to define requirements, assess the code and make the components work together.
A computer science degree gives you more room to move between software development and fields such as artificial intelligence, data science and cybersecurity. As AI automates more coding tasks, that flexibility is a reason to consider computer science even if your initial goal is to become a software engineer.
Can I Be a Software Engineer with a CompSci Degree?
Yes, it is possible to be a software engineer with a computer science degree. The two fields have a lot of overlap and the degree will prepare you for software engineering roles. Some of the best computer science programs in Australia offer software engineering or software development as majors.
A computer science degree provides a broad understanding of computing and technology, which can be applied to software engineering. Many software engineers have a degree in computer science or a related field, as it provides a strong foundation in programming, algorithms and software design.
But be aware that a software engineering degree may provide more specialized training in software development and project management. When you compare degrees, check the curriculum in detail to see which program best prepares you for the kind of career you want.
The distinction between algorithms and the practical design, creation, and maintenance of software is a helpful way to clarify the difference between computer science and software engineering. It also shows why the two fields overlap while still emphasizing different skills and goals.
A very informative read about a topic that I think was needed to be clarified for a while now. While comp sci covers the theory and development of computer systems, software engineers design and maintain software.
Computer science is focused on understanding the underlying principles and theories of computer systems, including computation, data systems, and software design. Software engineering, on the other hand, takes these theories and applies them to the practical development of software programs, including the design and implementation of frameworks, hardware, and applications. While computer science deals with the theoretical aspects of computer systems, software engineering deals with the practical application of these theories in the real world.
