What is full form of DFA and NFA?
DFA - deterministic finite automata NFA - non-deterministic finite automata
What is dfa and nfa?
DFA - Deterministic Finite Automata NFA - Non-Deterministic Finite Automata Both DFAs and NFAs are abstract machines which can be used to describe languages.
What is the difference between NFA and DFA with examples for each?

What is the proof that translating an NFA to DFA can be exponential?
Using the language: L_n = (0+1)^* 0 (0+1)^n (all the words that have the letter '0' n letters before their end) -There is a small NFA: this is easy - guess when there is going to be 0 and then count to n. -There is no small DFA: assume there is- then there are two n-sized vectors, u and v, such that they reach the same state q in the automaton. We'll observe the last place these two vectors differ - let that be the position m (m<=n). We'll create the words w1 and w2 that are: w1 = u 1^m and w2=v 1^m - assuming that u[m]=0 and v[m]=1, w1 is in L_n and w2 isn't. But the automaton accepts one iff it accepts the other - contradiction.
Write the Arden's method to convert an NFA to DFA with expression?
here first we looking on the given diagram and after this we select all the incoming input like in q1 all the input are q1=q2 0+ q1 1 or q2=q3 1 + q2 0 q1 is a state and when q2 sent 0 then its going to q1 so the value add into the q1 ok same in q2...
