3 Questions
What does 'DFA' stand for in automata theory?
Deterministic Finite Automaton
Which property distinguishes a DFA from a Nondeterministic Finite Automaton (NFA)?

Study Notes
DFA Basics
- DFA stands for Deterministic Finite Automaton.
Distinction from NFA
- The key property that distinguishes a DFA from a Nondeterministic Finite Automaton (NFA) is that a DFA has a unique transition for each input symbol in each state, whereas an NFA can have multiple transitions.
DFA Operation
- When a DFA reaches the end of the input string, it either accepts or rejects the string based on the state it is in, with the acceptance of the string depending on whether the final state is an accepting state or not.
Test your knowledge about Deterministic Finite Automaton (DFA) in automata theory. Learn about the distinguishing property of a DFA from a Nondeterministic Finite Automaton (NFA) and what happens when a DFA reaches the end of the input string.
