Processor Management Chapter 4

A policy used to ensure that jobs that have been in the system for a long time in the lower-level queues will eventually complete their execution.

The act of saving a job's processing information in its PCB so the job can be swapped out of memory and loading the processing information from the PCB of another job.

A job that will perform a great deal of nonstop processing before issuing an interrupt.
