The Ribbon is the long strip comprising tabs with buttons across the top of the main window within the PowerPoint interface. Since PowerPoint 2007, the Ribbon has replaced all the menus and toolbars that were found in PowerPoint 2003 and older versions. The Ribbon contains almost all the commands you need to work with your slides and is designed in a way that helps you quickly find the commands that you need to complete a task. You no longer have to search commands endlessly through many menus and sub-menus.
