CUET PG | operating system os | 2026

Assertion (A): Long-term CPU schedulers (Job Schedulers) control the degree of multiprogramming in a system.

Reason (R): The long-term scheduler decides which processes are brought from secondary storage (disk) into the main memory (ready queue).

Choose the correct answer:

Explanation

Assertion (A) is True:
The long-term scheduler (or job scheduler) determines how many processes are admitted to the system at any given time, thereby directly controlling the degree of multiprogramming.
Reason (R) is True:
The primary function of the long-term scheduler is selecting processes from the job pool (secondary storage) and loading them into main memory for execution.
Correct Explanation:
Reason (R) provides the exact mechanism—selecting and loading processes into main memory—that enables the scheduler to control how many programs reside concurrently in memory (the degree of multiprogramming).
