Question 4 [Points 5] Consider a system running 2 (two) CPU-bound tasks and 4 (four) I/O-bound tasks. Each l/O bound task issues an I/O operation once every 1 millisecond of CPU. Each I/O operation takes 4 milliseconds. Assume that there is only one l/O device (so multiple I/O requests may have to queue). Assume that the context switch takes 0.2 milliseconds. Assume that each CPU-bound requires 10 milliseconds of CPU to complete and each l/O-bound task requires 2 milliseconds of CPU time. Show through a Ganttt chart how the I/O and CPU are allocated and compute the average turnaround times for the CPU-bound and I/O bound tasks
