List-I A. Long-Term Scheduler B. Short-Term Scheduler C. Medium-Term Scheduler D. Context Switcher List-II Controls the degree of multiprogramming by choosing new jobs. Switches processes between main memory and disk swapping areas. Selects from ready processes to allocate the CPU core immediately. Saves and restores CPU states during process migration.

A-1, B-3, C-2, D-4 Explanation: Each component of the operating system's process scheduling framework performs a specific role: A. Long-Term Scheduler (Job Scheduler) 1 : Selects processes from the job pool on disk and loads them into main memory for execution, thereby controlling the degree of multiprogramming . B. Short-Term Scheduler (CPU Scheduler) 3 : Selects a process from the ready queue in main memory and allocates CPU execution time to it immediately . C. Medium-Term Scheduler 2 : Handles process swapping by moving processes between main memory and disk (secondary storage) to manage memory load efficiently. D. Context Switcher 4 : Responsible for saving the state (context) of a currently running process and restoring the saved state of the next process during execution switches. Thus, the correct match is A-1, B
