1. Data are raw facts.
2. Information is data that has been organized and converted into meaningful and useful context for end
users.
3. System is a set of interrelated components working together to achieve a common set of objectives,
By accepting inputs and producing outputs in an organized transformation process
4. the basic functions of any system are Input , Processing and Output.
5. a _ Information system_ is a set of interrelated components that collect, manipulate, and disseminate
data and information and provide a feedback mechanism to meet an objective.
6. the functions of a self-regulating system are Input , Processing , Output., Feedback and Control
