What Exactly is Computer and Information Sciences (CIS)?

Before diving into the specifics, let’s define what we mean by Computer and Information Sciences. Often, the terms Computer Science (CS) and Information Systems (IS) are used interchangeably with CIS, but there are subtle distinctions. At its core, CIS encompasses the theoretical and practical aspects of computation, information, and automation. It’s an interdisciplinary field that draws from mathematics, engineering, and cognitive science to address problems related to data, algorithms, hardware, and software.

Computer Science typically focuses on the theoretical foundations of computing, including algorithm design, data structures, programming languages, and computational theory. Information Systems, on the other hand, emphasizes the application of technology to solve business and organizational problems. CIS acts as a broader umbrella, encompassing both these areas and more. It recognizes the importance of both the theoretical underpinnings and the practical applications of computing.

Think of it this way: a Computer Scientist might develop a new algorithm for sorting data, while an Information Systems specialist might implement a database system to manage customer information for a company. A CIS professional understands both the algorithm and the database system and can bridge the gap between the theoretical and the practical.
