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.
Deadlocks can be detected while the program is running, by running cycle detection algorithms on the graph that de?nes the current use of resources. De?ne this graph as follows:
What are the various scheduling criteria for CPU scheduling? The various scheduling criteria are CPU utilization
