The Free On-line Dictionary of Computing (30 December 2018):

queue
dequeue
enqueue

    A first-in first-out data structure used to
   sequence objects.  Objects are added to the tail of the queue
   ("enqueued") and taken off the head ("dequeued").

   For example, an operating system might use a queue to
   serialise concurrent demands for a resource such as a
   printer, processor or communications channel.  Users might
   place files on a print queue and a background process or
   "demon" would take them off and print them.  Another common
   use is to pass data between an interrupt handler and a user
   process.
