6. Information DATA: facts that are needed to operate a business. INFORMATION: data organized into a form needed by an application. INFORMATION SYSTEM: hardware, software and procedures that maintain data and convert it into usable information.

7. Information System l An information system (IS) collects, processes, stores, analyzes, and disseminates information for a specific purpose. Like any other system, an information system includes inputs (data, instructions) and outputs (reports, calculations). It processes the inputs by using technology such as PCs and produces outputs that are sent to users or to other systems via electronic networks and a feedback mechanism that controls the operation.
