List-I (Scheduler Component) A. Job Queue B. Ready Queue C. Device Queue D.

A-2, B-1, C-3, D-4 Explanation: A. Job Queue -> 2: Holds the set of all processes that enter the system (including those on disk waiting to be admitted into main memory). B. Ready Queue -> 1: Holds all processes that reside in main memory (RAM) and are ready and waiting to be allocated CPU execution time. C. Device Queue -> 3: Maintained for each I/O device; holds the list of processes waiting for that specific hardware device. D. Medium-Term Scheduler -> 4: Performs swapping operations by moving processes out of main memory (RAM) to disk to reduce the degree of multiprogramming when memory overhead is high.
