Finite automata are mathematical models of computation used to design computer algorithms. They are abstract machines that can be in one of a finite number of states at any given time.
- DFAs (Deterministic Finite Automata) have exactly one transition for each input symbol
- NFAs (Non-deterministic Finite Automata) can have multiple or zero transitions for each input
- ε-NFAs extend NFAs with epsilon transitions that require no input symbol
- All three models have equivalent computational power (regular languages)
