Completion Time of Process(CT)- The time when the process completes its execution is completion time(CT). Turnaround Time(TAT)- The time difference between completion time and arrival time is TAT.
TAT= CT-ATWaiting Time(WT)-
WT= TAT-BT Total Interval(TAT)= Useful Time(BT)+ Wait Time(WT)Response Time(RT)- The first responded time or first scheduled time of process.]]>
