why pre-emptive?

mastguru 11 years ago replied

Pre-emptive scheduling takes effect when two jobs compete for the same job slots. If a high-priority job is pending, It can suspend a lower-priority job that is running, and then start the high-priority job instead.
So In real time, we have certain priority based jobs and pre-emptive scheduling can tackle it.
