Long term scheduler determines which programs are admitted
to the system for processing. It controls the degree of
multiprogramming. Once admitted, a job becomes a process.
Medium term scheduling is part of the swapping function.
This relates to processes that are in a blocked or
suspended state. They are swapped out of real-memory until
they are ready to execute. The swapping-in decision is
based on memory-management criteria.
Short term scheduler, also know as a dispatcher executes
most frequently, and makes the finest-grained decision of
which process should execute next. This scheduler is
invoked whenever an event occurs. It may lead to
interruption of one process by preemption.

lpng term schedular dictates what processes are to run on a
system and the degree of concurrency to be sopported at any
one time.

mid term schedular temporarily removes processes from main
memory and places them on secondary memory and vice versa.

short term schedular decides which of the ready ,in-memory
processes are to be executed next following a clock
interupt,an to i/o interupt , an os call or another form of
signal.
