With the invent of new technologies many new developments are seen in this field. Automata have been around since the prehistoric period. In this article, we have learned a brief introduction to the automata theory languages and computation. In theory of finite fields also we can find the application of Automata.In the field of biology, Cellular automata are useful.For applications in AI and in programming languages, Context-free grammar is very useful.

For text processing compilers and hardware designs, finite automata play a major role.Automata theory is very useful in the fields of Theory of computation, compiler productions, AI, etc.The applications of automata theory include the following. The transitions are Graphical Representation Tabular Form State Diagram State Diagram of Non-Deterministic Finite Automata Automata Theory Applications

In addition, another novel automaton design strategy, called reduction design, is described for the disjunctive rule matching (DRM) and counting. Let the Non-Deterministic Finite Automata be- A novel automaton design strategy, called linear design, is described to generate automata for matching and counting hierarchical patterns and apply it on SPM (Sequential Pattern Mining). Non-deterministic finite automata are represented with the help of the state diagram. Non-deterministic Finite Automata is represented as the set of 5 –tuple where(Q ,∑,δ,qo , F) It is also called Non-Deterministic Finite Automata, as it has a finite number of states. The automata where the output state for the given input cannot be determined is called Non-Deterministic Automata.
