Assumptions: 1. All processes are activated at time 0 2. Assume that no process waits on I/O devices. 3. After completing an I/O event, a process is transferred to the ready queue. 4. Waiting time is accumulated while a process waits in the ready queue. 5. Turnaround time is a total of (Waiting time )+( CPU burst time )+(I/O time) 6. Response time is the first measure of waiting time -arrival at time 0 until the first time on the CPU Process Data: process goes \{CPU burst, I/O time, CPU burst, I/O time, CPU burst, I/O time,......., last CPU burst \begin{tabular}{|l|l|l|l|} \hline Process (FCFS Results) & RT (response time) & WT (wait time) & TT (turnaround time) \\ \hline P1 & & & \\ \hline P2 & & & \\ \hline P3 & & & \\ \hline P4 & & & \\ \hline P5 & & & \\ \hline P6 & & & \\ \hline P7 & & & \\ \hline P8 & & & \\ \hline P9 & & & \\ \hline AVG & & & \\ \hline CPU UTILIZATION: & & & \\ \hline \end{tabular}
