Question

Adding an item to a queue is called an _____ , and removing an item from a queue is called a _____ ?

Answer 1

Adding an item to a queue is called enqueueing, and removing an item is called dequeuing. The queue operates on a first in, first out basis with elements added to the tail and removed from the head.

Step-by-step explanation:

Adding an item to a queue is called an enqueue operation, and removing an item from a queue is called a dequeue operation. In the context of data structures, a queue is a collection in which the entities in the collection are kept in order and the principle of "first in, first out" (FIFO) is followed. This means that the first element added to the queue will be the first one to be removed. When you enqueue, you add an element to the tail of the queue, and when you dequeue, you remove an element from the head of the queue.
