Medium term scheduling is segment of the swapping function. This relates to processes which are in a suspended or blocked state. They are swapped out of real-memory till they are ready to perform. The swapping-in decision is based on memory-management criteria.
Short term scheduler, also termed as a dispatcher performs most often, and creates the finest-grained decision of which process must perform next. This scheduler is invoked whenever an event happens. It might lead to interruption of one process by preemption.
