PPT-1 Introduction to Automata Theory

Reading Chapter 1 2 What is Automata Theory Study of abstract computing devices or machines Automaton an abstract computing device Note A device need not even be a physical hardware. Each one tape automaton defines a set of tapes a twotape automaton defines a set of pairs of tapes et cetera The structure of the defined sets is studied Various generalizations of the notion of an automaton are introduced and their relation to the of auxiliary . storage.
