A queue is a data structure in which elements are added at the end and removed from the front, following the "first in, first out" principle. In this sense, a printing queue fits this definition, as jobs are added to the end of the queue and printed one at a time, in the order they were received. The other options do not involve such a clear and straightforward process of queuing.
