Computer Science
How computers solve problems, from algorithms to systems.
Computer science is the study of computation itself: how to represent information, design efficient algorithms, and build systems that scale. You'll spend early semesters learning to think in code (usually Python, Java, or C++) and in logic, then move into the theory that underlies everything software touches, data structures, algorithms, computer architecture, and operating systems.
By junior and senior year, most programs let you specialize through electives, artificial intelligence, systems, security, graphics, or theory, while a capstone project asks you to design and build something substantial from scratch, often with a team.
Typical courses you might take
- ✓Intro to Programming
- ✓Data Structures & Algorithms
- ✓Discrete Mathematics
- ✓Computer Organization & Architecture
- ✓Operating Systems
- ✓Databases
- ✓Software Engineering / Systems Design
- ✓Theory of Computation
