Short-term (CPU scheduler)-selects from jobs in memory those jobs that are ready to execute and allocates the CPU to them.
Medium-term- used especially with time-sharing systems as an intermediate scheduling level. A swapping scheme is implemented to remove partially run programs from memory and reinstate them later to continue where they left off.
Long-term (job scheduler)-verifies which jobs are brought into memory for processing.

Evicting the most-recently used (MRU) page does very well on LRU's worst case. In general, however, MRU is a bad idea, since many programs exhibit temporal locality in their memory
Differentiate pre-emptive and non-preemptive scheduling In a pre-emptive scheduling technique, CPU can be taken away from a process if there is a requirement while in a non-pre
What is thrashing? It is a method in virtual memory schemes when the processor spends most of its time swapping pages, rather than implementing instructions. This is because o
