Deterministic Finite Automaton (correct)

Which property distinguishes a DFA from a Nondeterministic Finite Automaton (NFA)?

Ability to have multiple transitions from a state on the same input (correct)

Use of regular expressions for transition functions

Inability to recognize regular languages

Lack of a start state

What does a DFA do when it reaches the end of the input string?

Halts and rejects the input if in a non-accepting state

Continues processing the input string indefinitely

Switches to a different start state and continues processing

Halts and accepts the input if in an accepting state (correct)

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.
