Distinguish between dfa and nfa?
DFA stands for Deterministic finite automaton and NFA stands for Nondeterministic finite automaton.Formally, an automaton is made up of: were delta is the transition function. In a DFA, delta takes as input a state and letter and returns only one state. In an NFA, delta takes as input a state and letter but returns a set of states.An NFA accepts a word iff there exists a run of the automaton on it (intuitively, the automaton guesses an accepting run). A DFA has only one run on every word and therefore accepts a word iff the single run on it is accepting.
Can DFA simulate NFA?
Yes, any NFA can be converted into an equivalent DFA. because there is an equivalence in between an NFA and DFA
What is the difference between deterministic finite automata and non deterministic finite automata?
A deterministic Finite Automata)DFA will have a single possible output for a given input.The answer is deterministic because you can always feel what the output will be.A (Nondeterministic Finite Automata)NFA will have at least one input which will cause a "choice" to be made during a state transition,unlike a (deterministic Finite Automata)DFA one input can cause multiple outputs for a given (Nondeterministic Finite Automata)NFA.
Difference between deterministic finite automaton and non deterministic finite automaton?
The state machine described in the previous section is a deterministic finite automaton, in which each state is unique. What would make a finite automaton nondeterministic is if each state was not. For the example, if the state machine allowed the input to have any letter as the second letter for the word "person" to transition to the next, then the next state would not be unique, making it a nondeterministic finite automaton.

What is Minimum state automata?
A minimum automaton is the automaton that cannot be modeled with fewer states. Let a DFA D has n states that accepts a language L. If D is minimum then no other DFA can model L with number of states less than n.
Similarity bw NFA and DFA?
if a language is recognized by NFA then it can also be recognized by DFA so we can simply say that NFA=DFA
What is a DFA?
