Every job that enters the job queue is assigned a priority based on which its execution takes place. As simple it sounds, the processes with a higher priority will be executed first and then the processes with the lower priorities will be executed. If there are multiple processes in the queue with the same priority, then such jobs are executed in the order of their arrival often called as first come first served.
