Consider a set of traffic lights; the sequence of lights is
red. The sequence can be pictured
as a state machine, where the different states of the traffic
lights follow each other.
Notice that each state is dependent solely on the previous
state, so if the lights are green, an amber light will always
follow - that is, the system is deterministic. Deterministic
systems are relatively easy to understand and analyse, once the
transitions are fully known.
