What is the name for a system that translates human-readable domain names into IP addresses?
Difficulty: Easy
About this MCQ
This Easy Computer Networks MCQ checks one syllabus fact.
The question is: “What is the name for a system that translates human-readable domain names into IP addresses?”
The accepted answer is A. DNS. DNS is the fact required by “What is the name for a system that translates human-readable domain names into IP addresses” (option A). Option B (“UDP”) does not match the stem; it is a near-miss used to catch incomplete recall of DNS. Option C (“Subnet mask”) does not match the stem; it is a near-miss used to catch incomplete recall of DNS. Remaining alternatives (OSI model) fall outside the same rule and should be eliminated once DNS 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.
