With a four programs in memory and with 80% average I/O wait, the CPU utilization is ?
Correct Answer: A
Question 9 Explanation:
Given data
— Average I/O wait=80%
— Total programs in memory=4
— CPU Utilization=?
Step-1: To find CPU utilization, we have standard formula is 1-pn
Where,
— ‘n’ is number of process
— ‘P’ is waiting time for I/O.
Step-2: CPU Utilization=1-0.84
= 1-0.4096
= 0.5904 (approximation is 60%)
— Average I/O wait=80%
— Total programs in memory=4
— CPU Utilization=?
