Computer Science is the systematic study of algorithmic methods for representing and transforming information, including their theory, design, implementation, application, and efficiency.

The discipline emerged in the 1950s from the development of computability theory and the invention of the stored-program electronic computer. The roots of computer science extend deeply into mathematics and engineering. Mathematics imparts analysis to the field; engineering imparts design.

The BS in Computer Science program currently enrolls 1,397 students—979 accepted majors, 387 intended majors, 18 accepted subsequent bachelor's degree majors, and 13 intended subsequent bachelor's degree majors. (August 19, 2019)

The Main Branches of Computer Science

Artificial Intelligence (AI) researchers now predict that computers will be able to perform tasks that were once considered the prerogative of human beings.
Focuses on developing fundamental techniques, prototype systems and applications in databases and information retrieval.
Programmming Language research focuses on type systems, program logics, language-based and differential privacy and security; language, compiler, and run-time design for reliable systems; static and dynamic analyses for real-time Android; run-time visualization and verification; adaptive memory management; language concepts for database programming; logic- and constraint-based systems.
Computer science theory assesses which problems are possible and feasible to solve through theories of computability, undecidability, complexity, reducibility, and approximability.

Other important topics in Computer Science include Computer Graphics, Databases, Networks and Protocols, Numerical Methods, Operating Systems, Parallel Computing, Simulation and Modeling, and Software Engineering.
