The clipboard isn't really a place, so much as it is a state. In other words, is a temporary holding status that allows you to "paste" into another location such as document. Think "cut and paste", where when you "cut" text, it's being held in the "clipboard" until you either "paste" it somewhere else, or until you "cut" something else, at which time what is in the "clipboard" is then either deleted or replaced.
In a desktop PC, the clipboard is a collection of "clippings" that can be used to paste from at a later time and can be many separate items of either related or unrelated clippings. You have far more control of the clipboard in a desktop PC, and you are limited to only one clipping at a time on the phone.
