Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In which automata, more than 1 transition is possible?
A
NFA
B
DFA
C
PDA
D
Both NFA and DFA
Explanation: 

Detailed explanation-1: -In a nondeterministic finite automaton (NFA), for each state there can be zero, one, two, or more transitions corresponding to a particular symbol. If NFA gets to state with more than one possible transition corresponding to the input symbol, we say it branches.

Detailed explanation-2: -As per the definition of DFA, so as NFA it can have only one initial state.

Detailed explanation-3: -Deterministic finite state automata (NFA) can only have one enabled transition at a time while a non-deterministic finite state automata (DFA) can have multiple.

Detailed explanation-4: -Deterministic Finite Automata (dfas) The deterministic finite automaton or DFA is a very simple machine. It has one read-only input tape, with the restriction that the tape head can only move from left to right and can never change direction. The DFA has no other tapes.

Detailed explanation-5: -A DFA has exactly one transition from every state on every symbol in the alphabet.
