The scheduler оf а single-cpu system hаs three prоcesses аnd is cоntext-switching between them. When a process performs IO it blocks for 5 time steps and when it executes next it enters the RUN:io_done state. Each process needs to run for 3 time steps to finish. The timeline for the first 9 timesteps and each processes' state is shown below: Time PID: 0 PID: 1 PID: 2 CPU IOs 1 RUN:io READY READY 1 2 BLOCKED RUN:cpu READY 1 1 3 BLOCKED RUN:io READY 1 1 4 BLOCKED BLOCKED RUN:io 1 2 5 BLOCKED BLOCKED BLOCKED 3 6 BLOCKED BLOCKED BLOCKED 3 7 RUN:io_done BLOCKED BLOCKED 1 2 8 RUN:io BLOCKED BLOCKED 1 2 9 BLOCKED RUN:io_done BLOCKED 1 2 What is a possible state for the three processes at timestep 10, the next timestep?
