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 informationtechnologies (hardware and software) are required. The purpose for an informationsystem defines who it is for and what they need. Information systems give riseto ethical issues for people directly and indirectly involved with them. Theyhave a social impact on the environment in which they operate.
