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?
