(DFA and NFA) VS (Moore and Mealy) Machines
Like DFA and NFA Automata Machine, the Moore and Mealy are also Automata machines. Moore and Mealy’s machine also accepts regular languages like DFA and NFA.
(DFA and NFA) VS (Moore and Mealy)
| Sr. | DFA and NFA Machines | Moore and Mealy Machine |
| 1 | In NFA, there is no dedicated path for each input from each state. | For the Moore and Mealy machines, there must be a dedicated path for each input from each state, like DFA. |
| 2 | There are one or more than one final state in DFA and NFA Machines. | There is no final state in Moore and Mealy Machines. |
| 3 | DFA and NFA Machines take the inputs and do not give the output. | Both Moore and Mealy Machines take the inputs and provide the output as well |
| 4 | Both DFA and NFA check the acceptance of the given string. | The main concern is output rather than acceptance of input. |
| 5 | DFA can be converted into NFA Machines and vice versa. | Moore can be converted into Mealy Machines and vice versa. |
Note: DFA and NFA have no relation with Moore and Mealy Machines.
