Functionalities of a computer bold text
Any digital computer carries out five
functions in gross terms:
- Takes data as input.
- Stores the data/instructions in its memory and use them when required.
- Processes the data and converts it into useful information.
- Generates the output
- Controls all the above four steps.
Functions of an Information System(IS)
•Input
•Processing
•Output
•Feedback
the raw data that the system will manipulate and the activity of gathering that data
Input
the action that an information system completes when it converts or transforms data to generate useful information.
Processing
the useful information-usually in the form of documents, reports, and transaction data- that
an information system produces.
Output
output that guides adjustments or changes to an information system’s input or processing activities.
Feedback

- Smell-O-Vision
- Smell-O-Text
- Digital lollipop
was a system that released odor during the projection of a film so that the viewer could “smell” what was
happening in the movie. The technique was created by Hans Laube and made its only appearance in the 1960 film Scent of Mystery, produced by Mike Todd, Jr., son of film producer Mike Todd. The process injected 30 odors into a movie theater’s seats when
triggered by the film’s soundtrack.
