window

1. In general, a clearly marked (usually rectangular) semiautonomous area on a display that you can manipulate in a number of ways (for example, by moving the window). Window managers add standard decorations to windows. 2. In the X Window System, any area that receives events from the X server. One window can contain dozens of other windows: one for each widget.

window manager

In the X Window System, a program that oversees the position, layering, and decoration of windows. The window manager also provides the user with window controls to manipulate windows. Normally, the controls on all windows have a uniform look. Windows can request special treatment with window manager hints.
