Admission to Degree Program

The degree programs in the Department of Computer Science carry special enrollment limitations. Please see the college advisement center for specific details.

The Discipline

Computer science, even though it is a relatively new field, touches virtually every area of human endeavor. It is the systematic study of the algorithmic processes—their theory, analysis, design, efficiency, implementation, and application. Fundamentally, computer science is a science of abstraction—creating the right model for a problem and devising the right computer manipulations to solve it.

The BS curriculum is accredited by the Computer Science Accreditation Commission of the Computing Sciences Accreditation Board (CSAB).

The degree programs in computer science concentrate on the fundamental techniques and knowledge used in designing and implementing information processing systems, with emphasis on systems software design and computer organization.

Career Opportunities

Graduates from the Computer Science Department find ready employment in almost any area of computer use.
