All of the mentioned
|
Detailed explanation-1: -a) It can’t remember arbitrary large amount of information. b) It sometimes recognize grammar that are not regular. c) It sometimes fails to recognize regular grammar. Explanation:Because there is no memory associated with automata.
Detailed explanation-2: -Limitations of Finite Automata The defining characteristic of FA is that they have only a finite number of states. Hence, a finite automata can only “count” (that is, maintain a counter, where different states correspond to different values of the counter) a finite number of input scenarios.
Detailed explanation-3: -1 Answer. The correct choice is (a) It can’t remember arbitrary large amount of information. The explanation: Because there is no memory associated with automata.
