Computer science is the study of how computers can be used to solve a wide range of problems. At its most basic, computer science looks at how to transmit and transform information using computers. This field integrates topics from mathematics, physics, engineering and design. The field of computer science has been around in some form since as early as the 17th century!
Computer science can be split into practical and theoretical fields. Within these disciplines there are many subfields which look at various computer science concepts. Professional computer scientists generally lean towards the theoretical side of computer science. Other titles such as computer or software engineer deal with the more practical side of computer science.
Theoretical computer science includes abstract topics exploring math, physics and how computers work. These include topics such as computational complexity theory and the theory and design of programming languages. These topics focus on examining how computers can be used to efficiently complete tasks. This requires an understanding of the foundations of computer science such as formal logic, cryptography and probability theory. Though these topics are often abstract, they have real-world applications. Research from these fields enables and improves the technology we use on a daily basis.
Professional computer scientists need experience throughout the field, they should understand:
- Theoretical expertise that they can creatively apply to new problems
- Theoretical basis of their work to develop efficient algorithms
- Practical software engineering tools and patterns used to develop maintainable, interpretable code
- Application domain in order to effectively address problems
Computer scientists have many career options. These range from abstract research to solving real-world problems. Computer scientists are often employed by software companies and research institutions. However, the widespread use of computers means computer scientists work in many diverse fields.
What Does a Computer Scientist Do?
The role of a computer scientist is to apply concepts from computer science to create efficient solutions. The exact goals and responsibilities of a computer scientist vary between organizations and jobs:
- In academia – computer scientists may focus on expanding computational theory as well as educating the next generation of computer scientists.
- Computer scientists in various other industries will focus on finding ways to improve efficiency of real-world computer systems.
- Working alongside computer engineers and software engineers, computer scientists should be able to effectively communicate their work to these teams, as well as to non-technical stakeholders.
