Computer science (CS) spans the range from theory through programming to cutting-edge development of computing solutions. Computer science offers a foundation that permits graduates to adapt to new technologies and new ideas. The work of computer scientists falls into three categories: a) designing and building software; b) developing effective ways to solve computing problems, such as storing information in databases, sending data over networks or providing new approaches to security problems; and c) devising new and better ways of using computers and addressing particular challenges in areas such as robotics, computer vision, or digital forensics (although these specializations are not available in all computer science programs). Most computer science programs require some mathematical background.

What is Computer Science?

Computer Science is the systematic study of the feasibility, structure, expression, and mechanization of the methodical processes (or algorithms) that underlie the acquisition, representation, processing, storage, communication of, and access to information, whether such information is encoded in bits and bytes in a computer memory or transcribed ingenes and protein structures in a human cell. The fundamental question underlying all of computing is: whatcomputational processes can be efficiently automated and implemented?To tackle this seemingly simple question, computer scientists work in many complementary areas. They study the verynature of computing to determine which problems are (or are not) computable. They compare various algorithms todetermine if they provide a correct and efficient solution to a concrete problem. They design programming languages to enable the specification and expression of such algorithms. They design, evaluate, and build computer systems that can efficiently execute such specifications. And, they apply such algorithms to important application domains.

Why Computer Science?

In 1943, Thomas J. Watson, Chairman of IBM declared: “I think there is a world market for maybe five computers.” A few billion computers later, there is a temptation to fall into Watson’s embarrassing underestimation of the potential thatcomputing may have on our society. Indeed, in a few decades, “one computer per capita” may sound as outrageous as a“world market of five computers” sounds today. Computer scientists envision a world in which computing is pervasive andseamless. The golden age of computing (and of computer scientists) has barely begun. Students choose to major in computer science for a variety of reasons. Many of our students graduate to rewarding computer-related careers in software engineering, system administration and management, research and development inindustrial and governmental laboratories. And, since computer technology has transformed almost all disciplines, manyof our graduates use their computer science major (and the analytical skills it instills) to prepare them for a career in other disciplines such as medicine, law, education, physical and life sciences, social sciences, and humanities. Demandfor graduates well-versed in computer science is high and is expected to continue to grow as the information age comes of age!
