Consider the following statements and choose the correct one: (A) Job schedulers select processes from the pool and load them into memory for execution. (B) Short term scheduler selects among the processes that are ready to execute and allocates the CPU to one of them. (C) Medium term scheduler increases the degree of multiprogramming. Choose the correct answer from the options given below:
Show Hint
Differentiate schedulers by their roles: Job (long-term), short-term, and medium-term manage processes at different execution stages.
Job schedulers select processes from the pool and load them into memory for execution.
Short-term scheduler selects among the processes that are ready to execute and allocates the CPU to one of them.
Medium-term scheduler increases the degree of multiprogramming.
(A) only.
Show Solution
The Correct Option isB
Solution and Explanation
- (A): True. Long-term (job) schedulers manage the process pool by moving processes into memory for execution.
- (B): True. Short-term schedulers manage processes ready for execution and allocate CPU resources.
- (C): False. Medium-term schedulers manage memory by suspending and resuming processes; they do not directly increase the degree of multiprogramming.
