C OMPUTER S CIENCE Mr. Mohammed Rahmath

C OMPUTER S CIENCE Definition: Computer science (or computing science ) is the study of the theoretical foundations of information and computation and their implementation and application in computer systems. Computer science began to be established as a distinct academic discipline in the 1960s Focuses on the process of computing through several areas of specialization, including theory, algorithms, data structures, programming concepts and languages.

I NFORMATION T ECHNOLOGY AND S YSTEMS Information System : An Information System (IS) is the system of persons, data records and activities that process the data and information in a given organization, including manual processes or automated processes. Mr. Mohammed Rahmath

A PPLICATIONS OF INFORMATION SYSTEMS Information systems deal with the development, use and management of an organization's IT infrastructure. The study of information systems, focuses on why and how technology can be put into best use to serve the information flow within an organization. Mr. Mohammed Rahmath
