The behavior of an automaton is to alternately wait in a state and perform
a transition or event. We may think of the state as bearing information
representing the “knowledge” of the automaton when in that state,
and the event as modifying that information. At the same time we may
think of the event as taking place at a moment in time, and the state as
modifying or whiling away time.
