Meaning – The term pop-up window, refers to a movable window, fixed in size, in which a user provides information required by an application so that it can continue to process a user request.
Usually, the pop-up window contains a menu of commands and stays on the screen only until you select one of the commands. It then disappears.
A special kind of pop-up window is a pull-down menu, which appears just below the item you selected as if you had pulled it down.
Pop-up windows are often generated by websites that include pop-up advertisements. They typically appear when a user visits a page or closes a window. Some pop-up ads show up in front of the main window, while others show up behind the main browser window.
Example of usage – “Regardless of where pop-up advertisements appear on your screen, they can be pretty annoying. Fortunately, browser developers have realized this and most Web browsers now include an option to block pop-up windows.”
