In computing, to remove an item from a queue data structure; to take from the front of a line or waiting list in order.
From 'de-' (to remove) plus 'queue' (a line or waiting list), a computing term created in the mid-20th century.
Computer scientists use 'dequeue' constantly when processing data—every time your web browser loads images in order, or your printer handles jobs, it's 'dequeuing' items one by one from a list.
