Computer science is the study of the engineering, theory, and experimentation that go into creating and using computers. It involves taking a methodical, scientific, and practical approach to computation and its applications, as well as a methodical look at the viability, organization, expression, and mechanization of the methodical procedures (or algorithms) that underpin information gathering, representation, processing, storage, communication, and access. The study of automating scalable algorithmic processes can be a more concise and alternative definition of computer science. Computational systems design and theory are the areas of expertise for computer scientists.
