In a 2 or 4 way CPU environment, can an application make
use of the processing power directly?

Or does the operating system acts as the middle man
between CPU resource and application? I was once told that
a PC system works on a tiered or layered architecture such
that any installed software talks to the OS , and the OS
talks to the harware, in this case, the CPU. Is this still
correct? Appreciate any input. Thx.

In any multitasking environment the OS acts as the middle man controlling
how much CPU time the applications get.
