volume_mute

Event-driven modeling is based on the assumption that:

A system has a finite number of states, and events (stimuli) may cause a transition from one state to another

A system has no internal state and responds identically to the same input regardless of history

A system's behavior is completely determined by the sequence of user inputs

A system processes data in a single continuous pipeline from input to output

Correct Answer

A system has a finite number of states, and events (stimuli) may cause a transition from one state to another

Explanation

Event-driven modeling is based on the assumption that a system has a finite number of states and that events (stimuli) may cause a transition from one state to another. For example, a valve control system may move from 'Valve open' to 'Valve closed' when an operator command event is received. This view is particularly appropriate for real-time systems.
