What does DNS stand for?

• A. Digital Network Service.
• B. Domain Name System.
• C. Data Name Server.
• D. Dynamic Name System.

Answer: (B)

DNS is the system that lets people use easy-to-remember addresses like example.com instead of long numerical IP addresses. It stands for Domain Name System because it’s the global, hierarchical setup that translates domain names into the IP addresses computers use to locate resources on the network. When you access a domain, your device asks a DNS resolver, which may check its cache and then query a chain of servers (root, top-level domain, and authoritative name servers) until it returns the correct IP address so the connection can be made. The other options don’t fit what this system does: Digital Network Service isn’t the established term for translating names to numbers, Data Name Server isn’t the standard name for the whole system, and Dynamic Name System isn’t the recognized name and could imply a different concept.
