DNS stands for Domain Name System.

• A. Domain Name Service
• B. Domain Name System
• C. Domain Name Address
• D. Domain Name Protocol

Answer: (B)

DNS is the Domain Name System—the networked system that translates human-friendly domain names into the numeric IP addresses computers use. This mapping lets browsers connect to the right server when you type a name like example.com. The word “System” signals the whole naming infrastructure, including the database of names, the distributed servers, and the rules they follow. The other options miss the scope: “Domain Name Service” would imply just a service rather than the full naming framework, “Domain Name Address” points to the result rather than the mechanism, and “Domain Name Protocol” would refer to the communication rules of a single protocol rather than the complete system.
