Test: Equivalence of NFA & DFA - Computer Science Engineering (CSE) MCQ

: NFA is said to be closed under the following operations:
a) Union
b) Intersection
c) Concatenation
d) Kleene
e) Negation

 We use the construction method to prove the validity of closure properties of regular languages. Thus, it can be observe, how tedious and complex is the construction of a DFA as compared to an NFA with respect to space.

There are many applications of finite automata, mainly in the field of Compiler Design and Parsers and Search Engines.

Thompson Construction method is used to turn a regular expression in an NFA by fragmenting the given regular expression through the operations performed on the input alphabets.

Idle is the state when data in form of packets is send and returns if NAK is received else waits for the NAK to be received.

Finite state automation is used in Lexical Analyser, Computer BOT (used in games), State charts, etc.

Explanation: We need to make the number of a as fixed i.e. 2 and b can be 2 or more. Thus, using this condition a finite automata can be created using 1 states.
