Describe the differences among short-term, medium-term, and long-term scheduling.

 

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.
