2) Level 3(the operating system machine level) is usually a hybrid level. Most of the instructions at this level are also in the ISA level, i.e level 2. Those level 3 instructions that are identical to level 2's are executed directly by the microprogram or hardware control(at level 2), not by the operating system(at level 3). Is this a good execution choice? why or why not?
