It changes the viewable area of the graphics page without changing the graphics page.
It is like standing in a room looking at the outside through a window.
Depending upon where you stand in the room you see different areas of the outside.
In games it can be used like above, say you put up and image and move the viewport around you can simulate looking through a telescope kinda of effect.
Also, it can be used in wipes and fades and transitions.
It is up to your imagination.
