Question
Suppose we have two identical processes. These processes have unknown number of unknown sized CPU and I/O bursts. They are run on a systme with one cPU , one I/O device and no buffering.
-If the processes are run one after another, they take a total of 10 minutes to excute.
-If the processes are run concurrently with FIFO scheduling, then they take a total of 5 minutes( or a little higher, but under 6 mins) to execute (not a typo).
Answer the following questions:
A) What do you think is an educated guess of the total CPU usage of each process?
B) What do you think is an educated guess of the total I/O usage of each process?
C) If the processes are run under round robin, the total execution time will falll under what range?
Explanation / Answer
As per your requirement the below one is solution please follow it the following educated guess given for each options
A)
In the given scenario the CPU usage of the process is 3 minutes and 2 minutes each.
B)
I/O usage is also 3 minutes and 2 minutes each.
C)
In this case the execution will finish in 7-8 minutes.
