The book is praised for its exam-oriented approach, solved examples, and concise explanations — making it popular in Indian universities (especially for Pune University, RTMNU, and similar).
Automata theory is the study of abstract machines (automata) and the formal languages they process. These machines are used to define whether an input string is "accepted" or "rejected" based on a set of predefined rules.
