In NFA, every single pair of input symbols and states may contain many possible next states. The next possible state is clearly set in DFA.

The full form of NFA is Nondeterministic Finite Automata (NFA). The full form of DFA is Deterministic Finite Automata. The total time required for running any input string in NFA is larger than that in comparison to DFA. The total time required for running any input string in DFA is less than what it is in NFA. The number related to the next state/ states is either zero or one. The number related to the next state is one. NFA is more easily constructed in comparison to DFA. Given its complex nature, it is tougher to construct DFA. It is not possible to use backtracking at all times in the case of NFA. It is possible to use backtracking in DFA. NFA rejects the string in the event of all branches dying or refusing the string. NFA is like multiple small machines that are performing computational activities at the same time.ДFA rejects the string in case it terminates in a state that is different from the accepting state. No specifications are needed from the user with respect to how certain symbols impact the NFA.ДFA is not capable of using an Empty String transition.ДFA can be best described and understood as one machine. Basis of DifferenceДЇor each symbolic representation of the alphabet, only a singular state transition can be attained in DFA. The main difference between DFA and NFA, the two classes handling the transition functions of finite automata/ finite automaton theory, impact their behaviour in many ways.

NFA is like multiple small machines that are performing computational activities at the same time. DFA can be best described and understood as one machine. DFA refers to Deterministic Finite Automaton. NFA refers to Nondeterministic Finite Automaton. In this article, we aim to explain the difference between DFA and NFA in tabular form to help users understand what DFA is and what is NFA in the simplest terms.
