TechnologyFoundation
Information systems :• Three activities produce information organization
need:1. Inputs : captures raw data from organization or
external environment .2. Processing : converts raw data into meaningful form.3. Output : transform processed information to people
or activities that use it. feedback : output returned to appropriate
members of organization to help evaluate or correct input stage
