In the following timing, "ex", "iy", and "oz" represent execution, input, and output operations of process "P1"; and "Ex", "Iy", "Oz" represent execution, input, and output operations of process "P2". With respect to this timing explain:
A. How the advantage of multi-tasking in term of CPU utilization is shown?
B. How can we increase the CPU utilization? Explain how the CPU schedulers (e.g., long-term, short-term, medium-term) can be used to increase the CPU utilization. Draw a new timeline for CPU in which you can show the increase to the CPU utilization.
