Answer:microsoft Excel ribbon is the row of tabs and icons at the top of the Excel window that allows you to quickly find, understand and use commands for completing a certain task. It looks like a kind of complex toolbar, which it actually is.
The ribbon first appeared in Excel 2007 replacing the traditional toolbars and pull-down menus found in previous versions. In Excel 2010, Microsoft added the ability to personalize the ribbon.
The ribbon in Excel is made up of four basic components: tabs, groups, dialog launchers, and command buttons.
Ribbon tab contains multiple commands logically sub-divided into groups.
Ribbon group is a set of closely related commands normally performed as part of a larger task.
Dialog launcher is a small arrow in the lower-right corner of a group that brings up more related commands. Dialog launchers appear in groups that contain more commands than available space.
Command button is the button you click to perform a particular action.
