Question
Which of the following is a component of a Pushdown Automaton (PDA)?A) QueueB) StackC) TapeD) Register
Solution
The correct answer is B) Stack. A Pushdown Automaton (PDA) is a type of automaton that employs a stack to process context-free languages. The stack is a crucial component of a PDA, allowing it to keep track of symbols and their order, which is essential for recognizing context-free languages. The other options, Queue, Tape, and Register, are not components of a Pushdown Automaton.
