Consider a uniprocessor system where new processes arrive at an average of five processes per minute and each process needs an average of 6 seconds of service time. What will be the CPU utilization ?
Correct Answer: B
Question 881 Explanation:
5 processes arrives in 60seconds.
Service time for 1 process——–> 6sec
Service time for 5 processes——> 5*6 sec
= 30 seconds
CPU utilization = (30/60)*100
= 50%
Service time for 1 process——–> 6sec
Service time for 5 processes——> 5*6 sec
= 30 seconds
CPU utilization = (30/60)*100
= 50%
80 %
50 %
60 %
30 %
