CLASS: SS1 WEEK 11 TOPIC: INFORMATION SYSTEMS

Content: Information systems contain information about important people, places and things within the organization. By information, we mean data that have been converted or processed into meaningful form for human being use. Data in the other words are streams of raw facts representing events happening in an organization or immediate environment before they are organized and arranged into a form that people can use. Three main processes are important in an information system, which are input, processing and output. Input collects raw data from within the organization, from its immediate environment as the case maybe. Processing converts this raw input into more meaningful form. Output conveys the processed information to the people. Information system also needs feedback. Feedback is the output given back to appropriate members of the organization to help them evaluate or correct the input stage. DATA PROCESING Data processing is the stage involved in converting data into meaningful information. It entails collection of data from the scratch to the end. This processing is usually assumed to be automated and running on a computer. Sometimes data processing system is often referred to as information system.
