ELI5: Why on a computer screen does the cursor disappear when moved to the right/bottom edges, but not at the left/top edges?

Note: I'm using Windows 7. Not sure if it does this on other operating systems, or even if it's dependent on the OS rather than my monitor, or something else. I've always noticed this, but I never really gave it any thought until now.

The cursors 'point' is the very tip of the arrow and this cant leave the boundary of the working area (so your screen).  When moved to the bottom right of the screen, the cursor is still on screen just the rest of the white arrow is not.
