(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.
