In Macintosh and PC computers, and some other systems, the clipboard is a virtual memory holding area where data can be temporarily stored for certain tasks. The most common use of the clipboard is for copy (or cut) and paste operations. When you Copy a line of text, a graphic image, audio sample, etc. it is stored on the clipboard where it remains until you replace it with something else. In the Mac the contents of the clipboard can be viewed under the edit menu when the Finder is the active application. In Windows systems you can view it by looking under the Start Menu/Accessories/System Tools/Clipboard Viewer. Some Windows programs allow you a choice to append data to the clipboard or overwrite it each time something new is copied.
