(n.) A small box that appears on the display screen to give you information or to warn you about a potentially damaging operation. For example, it might warn you that the system is deleting one or more files. Unlike dialog boxes, alert boxes do not require any user input. However, you need to acknowledge the alert box by pressing the Enter key or clicking a mouse button to make it go away.

Alert boxes are also called message boxes.
