QUEUEs: is a list with access only at the front and rear of the list. That is, items are inserted (enqueued) at the rear of the queue, while deletions (dequeue) occur at the front.
A queue is useful for maintaining waiting lists; mostly, queues are used in simulation studies, hospital emergency ward and printing jobs within OS. For some applications queues are modified to prioritize items. That is, when removing items, the item with the highest priority is selected; this is called a priority queue.
