The green line is total CPU time; the red line is Kernel time. The gap between the two is User time. These two modes aren't mere labels; they're enforced by the CPU hardware. If code executing in User mode attempts to do something outside its purview-- like, say, accessing a privileged CPU instruction or modifying memory that it has no access to -- a trappable exception is thrown. Instead of your entire system crashing, only that particular application crashes.

That's the value of User mode. Only rings 0 Kernel and 3 User are typically used. If we're only using two isolation rings, it's a bit unclear where device drivers should go-- the code that allows us to use our video cards, keyboards, mice, printers, and so forth. Do these drivers run in Kernel mode, for maximum performance, or do they run in User mode, for maximum stability?
