window manager
the portion of an operating system that gives the programmer an interface for displaying within a window without concern for where on the screen the user has moved it or resized it and without concern for when or how windows overlap. The window manager provides the user with the ability to manage windows, by moving them, resizing them, minimizing and maximizing them, closing them, bringing them to the front and sending them behind other windows, and possibly even providing capabilities for automatic layout of the windows.
