Suppose P$1,$ P$2,$ P$3,$ P$4$ are in this order in the Ready Queue, and that the following sequence of

events occurs:

Time $10$: P$1$ invokes write

Time $15$: P$2$ invokes write

Time $25$: P$3$ invokes read

Time $30$: Interrupt $($P$1\text{'}$s write complete$)$

Time $40$: Interrupt $($P$3$s read complete$)$

Time $45$: P$4$ terminates

Time $50$: P$1$ terminates

There is no noon of a me slice and a process yields to another process only when it invokes an I$/$O operaon $($read$/$write$)$ or terminates.
