Question

consider a time sharing system with three processes in the ready state simultaneously on an average each process spends 80% of its time in I/O wait. then what will be the CPU utilization rate?​

Answer 2

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 %.
