A system is a set of components (subsystems) that operate together to achieve certain objectives. The objectives of a system are realized in its outputs. An information system is a system that accepts data resources as input and processes them into information products as output. An information system depends on the resources of people (end users and IS specialists), hardware (machines and media), software (programs and procedures), data (data and knowledge basis), and networks (communications media and network support) to perform input, processing, output, storage, and control activities that convert data resources into information products. This information system model highlights the relationships among the components and activities of information systems. It provides a framework that emphasizes four major concepts that can be applied to all types of information systems: People, hardware, software, data, and networks are the five basic resources of information systems. People resources include end users and IS Continue reading
