The title bar is that part of a window where the title of the window appears. In most graphical operating systems this is at the top of the application window.

The title bar often contains system commands for the window such as a maximize, minimize and close button, and may include other content such as an application icon, a clock, etc..

Most web browsers will render the contents of the title HTML element in their title bar, often pre- or postfixed by the application name.
