WebFinite-state machines provide a simple computational model with many applications. Recall the definition of a Turing machine: a finite-state controller with a movable read/write head on an unbounded storage tape. If we restrict the head to move in only one direction, we have the general case of a finite-state machine. The sequence of symbols WebThe read/write head is programmable.
