What is the defintion of a computer cursor?

The computer cursor is the little arrow (or whatever you have set it as) that moves about the screen when you move your mouse, or finger on a trackpad. You use it to click things, drag things around, highlight Words, and things to that effect. When the cursor looks like an animated glove, the item your cursor is hovering over may be clicked on for something to happen. If the computer is loading, it may appear as an hourglass, or on a mac, a "colorful spinning wheel of death." A computer cursor can also take the shape of a sWord or armored glove depending on what game or application you are using. This isn't the exact denotation, but close enough XD.
