Automata theory is a branch of the theory of computation that deals with the study of automata. An automaton is a simple computational model that can recognize patterns in strings of symbols. There are several types of automata, including:

While page 126 specifically varies by printing, it most commonly covers the or introductory concepts of Pushdown Automata (PDA) . Key Concepts often found in this section: theory of computation aa puntambekar pdf 126
Focuses on Context-Free Grammars (CFG), Pushdown Automata (PDA), and parsing techniques.
Before diving into abstract machines, the text establishes the fundamental building blocks of computation: A finite, non-empty set of symbols (e.g., Automata theory is a branch of the theory
