equivalence of nfa and dfa ppt

Does every NFA have an equivalent DFA?
We prove that every NFA has an equivalent DFA by showing how to construct a DFA N from N that recognizes the same language A.
N = (Q ,Σ ,δ ,q0,F ) defined as: 1.
What is the equivalence of NFA with DFA?
In principle, every NFA can be turned into an equivalent DFA.
The basic idea is that when a transition results in a set of states, we treat the set as one state in the equivalent DFA.
What is conversion of NFA to DFA?
Steps for converting NFA to DFA: Step 1: Initially Q' = ϕ Step 2: Add q0 of NFA to Q'.
Then find the transitions from this start state.
Step 3: In Q', find the possible set of states for each input symbol.
DFAs are useful for pattern recognition and parsing.
Nondeterministic Finite Automata (NFA): In an NFA, there can be multiple transitions defined from a state with the same input symbol, and it can also have epsilon transitions (transitions without consuming any input symbol).
