INFORMATION SYSTEMS (IS)
Is any combination of Information Technology and people's activities that support operations, management, and decision making.
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.
