Show answer & explanation
Correct answer: B
Correct matching: Spooling → Overlapping I/O and computation; Multiprogramming → Allows several jobs to improve CPU utilization; Time sharing → Allows many users to share a computer simultaneously by switching the processor frequently; Distributed computing → Access to shared resources among geographically dispersed computers in a transparent way.
Spooling: Queues I/O or print jobs so that I/O devices and the CPU can operate concurrently, enabling overlapping of I/O and computation.
Multiprogramming: Keeps multiple jobs in memory so the CPU can switch to another job when one waits for I/O, improving overall CPU utilization.
Time sharing: Rapid processor switching lets many users interact with the system simultaneously, giving the illusion of dedicated access.
Distributed computing: Makes resources on geographically dispersed machines available in a transparent way to users and programs.
