About this MCQ
This Easy Operating Systems MCQ checks one syllabus fact.
The question is: “What is the name for software that allows the operating system to communicate with a specific hardware device?”
The accepted answer is A. Device driver. Device driver is the fact required by “What is the name for software that allows the operating system to communicate with a specific hardware device” (option A). Option B (“Process”) does not match the stem; it is a near-miss used to catch incomplete recall of Device driver. Option C (“Virtual memory”) does not match the stem; it is a near-miss used to catch incomplete recall of Device driver. Remaining alternatives (Paging) fall outside the same rule and should be eliminated once Device driver is identified. Operating Systems questions of this type reward precise definitions rather than approximate associations. Operating Systems recall of this distinction is a regular item in FPSC, PPSC, NTS, and CSS papers.
