What is computer science?

Computer science focuses on applying computing, algorithms, and programming techniques to operating systems, artificial intelligence (AI), and informatics. Advances in machine learning, AI, and cybersecurity have led to growth in information technology.

Computers are used in nearly all fields of study and professions. Computer scientists create systems designed to understand big data structures, operationalize tasks, and innovate for the future.

As algorithms become more complex, the computer science field is expanding to include more subfields and concentrations.

Enrolling in an online course or degree program can be worth it to help you learn programming languages, explore principles of computer science, and gain new skills.

Why learn computer science?

  • You can qualify for opportunities in a high-growth field: The Bureau of Labor Statistics (BLS) projects nearly 318,000 annual job openings in computer and information technology from 2024 to 2034.
  • By studying computer science, you can become a problem-solver in high-impact fields like healthcare, cybersecurity, education, urban development, and many others.
  • In a 2025 edX survey, 36% of leaders listed AI and machine learning as a top skill for career advancement, 25% listed software development, 23% listed cybersecurity, and 14% listed cloud computing — all skills that require computer science expertise.

How to get started in computer science

The outset of your journey to learn computer science can feel daunting, but building a goal-oriented roadmap can help. You can follow these steps to get started in computer science with no experience:

1. Focus on foundations

Many computer science concepts draw heavily on logic and math. You can build strong foundations for computer science learning by ensuring you have solid knowledge in these areas.

Focus specifically on these areas:

  • Classical rule-based logic systems
  • Boolean logic
  • Algebra, calculus, discrete mathematics, and statistics

You can pursue many avenues for brushing up on your logic and math skills. Free, self-guided tutorials can help, especially if you already have background knowledge. You can also consider online math courses and programs for a more structured alternative.

Frequently asked questions

Can I learn computer science on my own?

Yes, you can learn computer science on your own by taking advantage of free or low-cost instructional resources, like video lectures and tutorials. As some employers prioritize hard, demonstrable skills over formal educational credentials, you should consider validating the skills you gain by earning a professional certificate.

Is computer science full of math?

Computer science draws extensively on mathematics, but to describe it as "full of math" overlooks some key considerations. Many areas of computer science use algebra, calculus, discrete math, and statistics. The extent to which you use these mathematical branches in your studies or job duties varies by specialization and role.

Schools and programs also use various strategies to teach computer science, and some approaches involve less math than others.

Will AI replace computer science?

Artificial intelligence might automate some entry-level computer science roles, particularly in areas like coding and basic programming. However, fears that AI systems will completely replace human computer science professionals do not align with the expert consensus.

Instead, AI might change the way computer scientists conduct their research and perform their job duties, rather than eliminating human roles.

Is a computer science degree worth it?

A computer science degree can help you qualify for high-paying and high-growth career opportunities. These programs also emphasize versatile, valuable technical skills that transfer well across many industries. From this perspective, a computer science degree often offers a strong return on investment.
