Thanx but In my opinion ....10 processors per minute ko...

60/10 = 6  sec ayegaa....

And service time = 4 sec...

 

So the fraction of time CPU is busy = service time / staying time

                                                          = 4 / 6

          = 2 / 3

Taking percentage fraction               = 2 / 3 × 100

          = 66.6%

So the CPU is busy for 66.6% of the time.

HERE WE GO CHECK THE SOLUTION...

Given that there are on an average 10 processes per minute.

So the arrival rate = 10 process/min.

Service time = 4 sec.

Hence the fraction of time CPU is busy = service time / staying time

= 4 / 10

=0.4

So the CPU is busy for 40% of the time

CS EXPERT ....

Answer this Question...of OPERATING SYSTEMS..CS604

 

Suppose there are number of processes running on a system. New process in this system arrives at an average of ten processes per minute. Each process requires an average of 4 seconds of service time. Estimate the fraction of CPU busy time in a system with a single processor.

 

Waiting..

Best Regards..
