Menu bar
A menu bar is a feature of most computer graphical user interfaces that implement windows. The menu bar allows the user to have point-and-click access to window-specific functions, such as saving a file, copying text, or opening a help window.
In Windows, the menu bar is located at the top of each window, just below the title bar. In OS X, the menu bar is located at the top of the screen and changes depending on which window is in focus.
