We worked with a series of mathematical models of computation -- deterministic and nondeterministic finite automata (DFAs and NFAs), push-down automata (PDAs), and finally Turing machines (TMs) -- to better understand the strengths and limitations of actual computers. We begin with a study of finite automata and the languages they can define (the so-called "regular languages."

Automata theory : the study of abstract computing devices, or ”machines” Before computers (1930), A. Turing studied an abstract machine (Turing machine) that had all the capabilities of today’ s computers (concerning what they could compute). Automata theory is a further step in abstracting your attention away from any particular kind of computer or particular programming language.
