What is the primary role of the Domain Name System (DNS) in computer networks?
A. To assign dynamic IP addresses to workstations on boot.
B. To resolve hardware MAC pointers to subnet masks.
C. To translate human-readable domain names into machine-routable numerical IP addresses.
D. To translate private IP paths to public gateway channels.
Answer: Option C
Solution (By JKSSB Mock Tests)
DNS translates alphanumeric domain names (like [www.example.com](https://www.example.com)) into the numerical IP addresses used by computers to route data.
Explanation:
127.0.0.1 is the standard loopback address. It lets a device route diagnostic traffic back through its internal software layer without hitting physical network lines.
Which device can be used to link two separate LAN segments that use different physical cabling profiles but share the same underlying protocol framework?
