Which term refers to a unique hardware identifier assigned to a network interface controller?
Difficulty: Medium
About this MCQ
This Medium Computer Networks MCQ checks one syllabus fact.
The question is: “Which term refers to a unique hardware identifier assigned to a network interface controller?”
The accepted answer is A. MAC address. MAC address is the person, body, or term that satisfies “Which term refers to a unique hardware identifier assigned to a network interface controller” (option A). Option B (“NAT”) does not match the stem; it is a near-miss used to catch incomplete recall of MAC address. Option C (“VPN”) does not match the stem; it is a near-miss used to catch incomplete recall of MAC address. Remaining alternatives (Router) fall outside the same rule and should be eliminated once MAC address is identified. Computer Networks questions of this type reward precise definitions rather than approximate associations. Computer Networks recall of this distinction is a regular item in FPSC, PPSC, NTS, and CSS papers.
- A. MAC address ✓
- B. NAT
Why not B: “NAT” is not correct. The accepted answer is A. MAC address. MAC address is the person, body, or term that satisfies “Which term refers to a unique hardware identifier assigned to a network interface controller” (option A). Option B (“NAT”)
- C. VPN
Why not C: “VPN” is not correct. The accepted answer is A. MAC address. MAC address is the person, body, or term that satisfies “Which term refers to a unique hardware identifier assigned to a network interface controller” (option A). Option B (“NAT”)
- D. Router
Why not D: “Router” is not correct. The accepted answer is A. MAC address. MAC address is the person, body, or term that satisfies “Which term refers to a unique hardware identifier assigned to a network interface controller” (option A). Option B (“NAT”)
