Important Parameters of Processes

• Arrival Time: It is ready to be executed.Process enter the ready state.
• Burst Time: The amount of CPU time that is required by processes to finish.
• Completion Time: The time at which the process finished at time.
• Turn around Time: The difference between Completion Time and Arrival Time.
• Waiting Time: Out of this entire time (TAT) it as executed only for some time and remaining time it just waited for CPU that is called Waiting time.

          WT=TAT-AT

• Response Time: What is the first time at which the process hits the CPU.So the first time at which process get schedule minus Arrival time

           CT-AT=BT+WT 
   
           TAT=CT-AT
