Difference between "queue" and "enqueue" [closed]

What is the difference between queue and enqueue given that both are verbs?

According to this Merriam-Webster link, definition of 'Queue' as a verb is-

queue verb \ˈkyü\ : to form or wait in a line

transitive verb : to arrange or form in a queue

and

intransitive verb : to line up or wait in a queue —often used with up.

See below two examples of both forms of this usage of queue as a verb -

The World's Food Fair, Boston. October 1896. Admission: 25 cents. Huge crowds throng the Mechanics Hall convention center. Women queue up for free samples from 200 different vendors: cereals, gelatins, extracts, candy, and custards. —Christopher Kimball, Cook's Illustrated, January & February 2008

and

The crowd was queuing at the snack bar.

And now look at this definition of 'Enqueue' as a verb from the Oxford Dictionaries-

enqueue:

VERB (enqueues, enqueuing or enqueueing, enqueued)

[WITH OBJECT] Computing Add (an item of data awaiting processing) to a queue of such items.

While "queue" has a relatively broad usage as a verb(with reference to line up/create a line), "enqueue" is mostly used in computing(specifically- data structures).
