Applications of Computer Science knowledge include almost every field from business to education, from humanities to social sciences, or from natural sciences to engineering. Therefore, the study of Computer Science contains many fields such as computer architecture, programming languages, computer networking, database systems, information management, artificial intelligence and numerical analysis.

The Cal State San Marcos undergraduate study in Computer Science emphasizes both theoretical foundations and practical applications. Students will learn algorithms, data structures, software design, the concepts of programming languages, computer organization, and computer architecture. The program stresses analysis and design experiences with substantial laboratory work, including software development.

The Computer Science major prepares students for careers in applications programming, system analysis, and software engineering, as well as for entrance into graduate and professional schools.
