Ring 0 = supervisor or kernel mode (unrestricted access)
Ring 3 = user mode (restricted access)

All unices operate in two modes. The Intel ix86 supports 4 "modes"
or "rings", or "levels", so only the two extremes are used.

Why not try a WEB SEARCH next time - The Internet is an amazing thing :-)

GGI = General Graphics Interface
