How does DNS enable human-friendly navigation on the internet?

• A. By allowing devices to communicate using domain names rather than numeric IP addresses.
• B. By providing free hosting for domain names.
• C. By caching all web pages locally on a device.
• D. By mapping domain names to physical addresses only on local networks.

Answer: (A)

DNS enables human-friendly navigation by translating domain names into numeric IP addresses that computers use to locate and connect to servers. When you type a web address, your device asks a DNS resolver to resolve that name, which queries a chain of servers (root, TLD, and authoritative servers) to return the correct IP. The browser then uses that address to establish a connection and load the site. Caching helps speed repeated lookups, so familiar names resolve faster over time, keeping navigation smooth and scalable across the internet. This mapping is not about hosting content, nor is it about storing entire web pages locally, and it operates beyond local networks by resolving names to addresses globally rather than to physical addresses like MACs.
