In very simple terms, a stack is a collection of objects in which objects are accessed in LIFO (Last In First Out) fashion. Whereas a queue is a collection of objects in which objects are accessed in FIFO (First In First Out) sequence.
What are the Differences between Stack and Queue?
Following are the major differences between these two data structures: In a stack, an object is pushed on top of the collection during insertion operation. In a queue, new object is inserted at the end. An object is removed from a stack from the top. In queue, object is removed from the beginning. In stacks, the two operations allowed are called push (insertion) and pop (removal). In queue, two possible operations are called enqueue (insertion) and dequeue (removal). In a stack we remove the item the most recently added; in a queue, we remove the item the least recently added. So these were the major differences between stack and queue data structures.
