16. The execution time for a program P on computer system X includes the time the CPU spends executing instructions
of the operating system on behalf of P.
17. A microprocessor system with a system clock frequency of 3 GHz will always execute programs more quickly than a
different microprocessor system running at only 2.5 GHz.
18. More code is written in high-level programming languages than assembly language because an assembly language pro -
gram is so closely tied to the underlying architecture of the machine that it is not possible to run an assembly langu -
age program written for processor X on a processor Y, with a different architecture.
19. If we know the average CPI for a program and the system clock frequency, then we can calculate the user CPU time.

Explanation / Answer

16.No-CPu time is the amount of time for which CPU was used for processing instructions of a computer program.

Execution time s the time during which a program is running ,in contrast to other program lifecycle phases .

17.Yes ,the higher the frequency the faster thebCPU computer works.

18.yes,the assembly language code is a machine dependent language.as it differs with the instruction set of the processors
