- input : what is put in, taken in, or operated on by any process or system
- output: what is produced, delivered, or supplied (data) by a process or system
In any solution you must clearly understand the specific inputs and outputs.
Diagram[edit]
This diagram is used from Johnstone, D., Bonner, M., & Tate, M. (2004) "Bringing human information behaviour into information systems research: an application of systems modelling" Information Research, 9(4) paper 191, Available at http://InformationR.net/ir/9-4/paper191.html
Example[edit]
As an autonomous car is traveling, a radar system scans in front of the vehicle. If an object is detected, the car MIGHT slow down, turn, sound an alarm, honk the horn, or a combination of all four.
The input in this case is the data produced by the radar. The output in this case is the control instructions to the car. Those output instructions might instruct the car to "slow down slowly" or "slow down very quickly".
Another example[edit]
Headlights are the lights in front of a car. Headlights can have the following states:
- off
- on
- low
- high
A car has a headlight sensor. If the sensor detects headlights AND the headlights are on,
Do you understand this?[edit]
