Complete the term: domain name ________.

Complete the term: domain name ________.

• A. System
• B. Protocol
• C. Service
• D. Locator

Answer: (C)

Domain name service is the part that translates human-friendly domain names into the numeric addresses computers use to locate resources on the network. This makes it a service: it provides a concrete capability that clients rely on to resolve names and connect to the right server. The domain name system (DNS) is the broader concept, but the core idea in this wording is the service that performs the name resolution. The other terms don’t fit as well: a system would refer to the whole infrastructure, a protocol is the rules used (DNS is indeed a protocol, but the question asks for the term describing the function you rely on), and locator isn’t the standard label used here.
