Where we use Automata ?

Use of Automata

Without understanding the reason behind the concept and its importance, We always find it tough to learn. As 'Automata Theory' is one of the core subjects in the Computer Science domain it is very important to keep the concepts clear. That will happen when we understand its importance and usefulness.

Automata Theory makes a significant impact in different fields of computer science and engineering are as follows:

• The main role of the automata theory is in the Compiler Design. The first phase of the compiler is called lexical analyzer which is based on finite automata. In the syntax analysis part, a common error called syntax error is checked by the rules of context-free grammar.
• The software for natural language processing (NLP) takes the help of the automata theory.
• Automata is useful for designing software for counting the occurrence of a particular word, pattern, etc., in a large text.
• The working principle of the software used for checking the behavior of digital circuits is based on the automata theory.
• The heart of the TCP/IP protocol is a finite state machine
• Sequence and vending machines
• Video games
• Text parsing
• Regular expression matching
• Speech recognition
