Computer science has become a foundational component of almost all industries, as computing technologies are used in nearly every aspect of modern life. Those who learn computer science skills can build careers in Information Technology, healthcare, finance, and energy, as well as other industries. Read on to learn more about these industries and career fields.

Information Technology (IT)

IT professionals use computer science concepts and tools to manage data, build and maintain computer systems, and create software applications. IT is an industry that includes many different job titles such as Computer and Information Research Scientists, Computer Network Architects, Computer Support Specialists, Computer Systems Analysts, Database Administrators and Architects, Information Security Analysts, and Network and Computer Systems Administrators. According to the U.S. Bureau of Labor Statistics (BLS), the median yearly wage for IT professionals is around $100,000, which is more than twice as much as the median annual wage for all occupations in the U.S. BLS also estimates that this industry will see job growth of 15% between 2021 and 2031.

The daily responsibilities of an IT professional depend on the person’s specific role. Computer and Information Research Scientists solve complex problems and design innovative uses for computer technology in the fields of business, medicine, science, and more. Computer Network Architects build local area networks (LANs), Intranets, wide area networks (WANs), and other data communication networks. Information Security Analysts protect a business’s computer networks and systems by planning and carrying out security measures. Computer Systems Administrators maintain computer networks’ day-to-day operations. These are just some of the many careers you can find in IT.


Computer science plays a crucial role in healthcare, from electronic medical records to imaging technologies and medical research. IT specialists help to ensure a hospital’s computers and networks run smoothly, maintaining patient records, allowing doctors to make digital notes, and more. Data Scientists clean, sort, and manage data and draw insights from that data. This information not only helps hospitals, but surrounding communities as well. For example, hospital data can be used to help track community spread of an illness, allowing local healthcare departments to respond accordingly.

Computer science also plays a role in the development of healthcare technology. Healthcare technology tackles challenges like creating robotic-powered prostheses, hearing aids, mobility devices, and more. These technological breakthroughs transform patients’ lives. Technological improvements also empower doctors and other medical professionals to detect medical issues earlier, more easily, and faster than ever before, allowing for preventive and proactive measures that save lives every day. 

One specific computer science role in the healthcare industry is that of a Health Information Technologist or Medical Registrar. These professionals analyze clinical data and make recommendations regarding computerized healthcare systems. According to BLS, the average annual salary for this position is around $55,000. It has an expected job growth of 17% from 2021 through 2031. Occupational Health and Safety Specialists or Technicians gather information and evaluate various work settings and protocols. They earn a yearly salary of around $75,000 on average. This job has a projected growth of 5%, which is in keeping with the national average.


Computer science is used extensively in finance for tasks such as algorithmic trading, risk management, and fraud detection.
