Difference between the scheduler









Difference between the scheduler





S.N.
Long-Term Scheduler
Short-Term Scheduler
Medium-Term Scheduler
1
It is a job scheduler
It is a CPU scheduler
It is a process swapping scheduler.
2
Speed is lesser than short term scheduler
Speed is fastest among other two
Speed is in between both short and long term scheduler.
3
It controls the degree of multiprogramming
It provides lesser control over degree of multiprogramming
It reduces the degree of multiprogramming.
4
It is almost absent or minimal in time sharing system
It is also minimal in time sharing system
It is a part of Time sharing systems.
5
It selects processes from pool and loads them into memory for execution
It selects those processes which are ready to execute
It can re-introduce the process into memory and execution can be continued.
