When the process is scheduled to run after some execution:

Question 2

CPU scheduling is a process which allows one process to use the CPU while the execution of another process is on hold(waiting time) due to unavailability of any resource like I/O etc, thereby making full use of CPU. Thus the task of CPU is to maximize its Utilisation. What among the following is not true to achieve that ?

Question 3

Consider the following 3 processes with the length of cpu burst time(in milliseconds). All processes arriving at the same time in order P1, P2, P3

If Round Robin Scheduling is used with time quantum of 1 Unit then average waiting time will be,
