What term is used to remove an item of data from the queue?

The term used to remove an item of data from a queue is "dequeue." In the context of data structures, a queue operates on a first-in, first-out (FIFO) principle, meaning that the first element added to the queue will be the first one to be removed.

When you perform the dequeue operation, you are actively removing an element that has been at the front of the queue, allowing the next element to become accessible as the new front. This is fundamental to the operation of a queue, ensuring that items are handled in the order they were added.

The other terms are associated with different data structures: "enqueue" refers to adding an item to the end of the queue, while "push" and "pop" are terms used in the context of a stack. In a stack, push adds an item to the top, and pop removes the item from the top, following a last-in, first-out (LIFO) principle. Therefore, in the context of queues specifically, "dequeue" is the accurate term for removing an item.
