Question

If there are n processes and each process waits p time in waiting state then cpu utilization is-:

Answer 1

CPU utilisation can be calculated by the formula - N ^P.

Here,

N = number of processes.
P = waiting time for each process.

CPU utilisation refers to the sum total of the work processed by it.

It is one of the most reliable measures of system performance.

Larger tasks take more time and simple tasks take lesser time.

Answer 2

A system used for scheduling allows a single process to use the CPU when the other is waiting.

This is making total use of the cycle of the CPU.

This leads to less utilization of the CPU.

In a system which runs only a single process the CPU cycles are forever lost.
