Computer science is the study of computation and algorithms, using a scientific and practical approach. Computation implies use of computing technology and any type of calculations. Computer science degrees cover the topics such as algorithms and protocols, that help in acquiring, representing, processing, storage, communication of and access to information.
The core subjects of computer science are the theory of computation, basic programming and the principles of computer hardware, data communications, algorithms, programming methodologies, discrete mathematics, calculus, numerical methods, operating systems and other topics. Is mathematics necessary to study computer science? Yes, math is essential for a career in this field. Usually, computer scientists and computer science professionals deal with software and software systems.
As the use of technology invades all domains of human activity, there is need for specialists in different branches. Some of the branches of computer science that are sure to be in the news in 2020s are:
- Artificial Intelligence (AI)
- Data Sciences
- Machine Learning
- Cloud Computing
- Web Development
- Mobile Computing
- Internet of Thing (IoT)
- Virtual Reality
- Augmented Reality
- Human Computer Interaction (HCI)
- Geographical Information Systems (GIS)
Many degree level courses include a 6-month or a year’s internship/training within the industry; this is invaluable in developing key skills and building contacts. If you have done mini or micro projects as part of your degree level course such as web development, app development, etc, it is recommended that you maintain a portfolio of your projects. It is important to learn atleast 2 programming languages thoroughly. Python and Java could be a good choice at this time.
Typical roles with degree in computer science are as university professor, software developer, database administrator, IT consultant, network engineer, information systems manager, data scientist, multimedia programmer, or games developer, cyber security specialist, ethical hacker, among many others.
If you choose to study computer science, be prepared for hard work, that could lead to working on the front line of the world’s greatest innovations. You will also be a life-long learner and adapt quickly to this rapidly changing field.
