Explanation

Stacks operate on LIFO (Last In First Out) principle, meaning the last element added is the first one removed. FIFO (First In First Out) is the characteristic of queues, not stacks. LIFO, piles, and push-down lists are all names associated with stack data structures, while FIFO specifically describes queue behavior.
