what is response time
the time from when a job enters the scheduler queue to the time its execution is complete
what is throughput?
the number of jobs that are fully executed in a given period of time (aka minimum schedule length)
what heuristic can be gained from the shortest job first algorithm
this algorithm produces the schedule with the minimum mean average response time
what heuristic can be gained from longest job first
this algorithm produces the schedule that has very close (although does not guarantee) to the maximum throughput
