8.1+Introduction+to+Information+Systems

An information system has a purpose in that it addresses the need(s) of a group or an individual. It performs the information processes of collecting, organising, analysing, storing/retrieving, processing, transmitting/receiving and displaying. Information processes involve computer and non-computer activities. For the processes to occur, participants (people), data/information and information technologies (hardware and software) are required. The purpose for an information system defines who it is for and what they need. Information systems give rise to ethical issues for people directly and indirectly involved with them. They have a social impact on the environment in which they operate.
