DNS stands for?

• A. Domain Name System
• B. Domain Name Service
• C. Directory Name System
• D. DNS Name Service

Answer: (A)

The concept being tested is the exact expansion and role of the DNS in networking. DNS stands for Domain Name System. It is the distributed naming system that translates human-friendly domain names (like www.example.com) into the numeric IP addresses that computers use to route traffic. This resolution process makes it possible to access sites without remembering IP addresses, and it involves a hierarchy of name servers that can be cached for efficiency. The other options aren’t correct because they change the official wording or meaning: Domain Name Service uses “Service” instead of the widely used “System,” which isn’t the standard term; Directory Name System isn’t the recognized naming; DNS Name Service isn’t the correct expansion.
