What are the components of Finite automaton model? The components of FA model are Input tape, Read control and finite control.

Depending on the current state and input symbol read from the input tape it changes state. NFA or Non Deterministic Finite Automaton is the one in which there exists many paths for a specific input from current state to next state. Deterministic Finite Automaton is a FA in which there is only one path for a specific input from current state to next state.

What is a regular expression? A regular expression is a string that describes the whole set of strings according to certain syntax rules.

These expressions are used by many text editors and utilities to search bodies of text for certain patterns etc. The regular expression R is given as: Context Free Grammar And Languages: What are the applications of Context free languages?
