It is becoz at the timer interrupt for eg: in case of Round Robin, it is the CPU which saves the state of the current process into the PCB and kernel takes control to use the scheduler to launch the next process. nephron answered Aug 31, 2018 nephron comment Share Follow See all 0 reply Please log in or register to add a comment.
