The CPU utilization rate is equal to 20 %.
Explanation:
- The CPU utilization measure is calculated using the average CPU use across the view's time period.
- The percentage of time that a component is doing work, divided by the entire amount of time in the time period, is referred to as utilization percent.
- The busy time of a CPU is used to process program instructions.
- Poor application performance might be indicated by high CPU use rates. Processes must wait in the processor queue for a prior process to complete execution when the CPU usage is high.
- CPU utilization rate = 100 - 80/ 100 * 100
- Therefore it is equal to 20 %.
