What is the primary role of the Domain Name System (DNS) in networking?
C: It encrypts data for secure communication between devices.
A: Routers use it to decide the best path for data packets.
B: It translates domain names into IP addresses.
D: It provides a protocol for remote control of devices over a network.
The correct answer is B because DNS is responsible for translating human-readable domain names into machine-readable IP addresses. When you type a website's domain name into your browser, DNS servers take that domain name and turn it into an IP address so your computer can access the website. Incorrect answers are tempting but do not accurately describe the primary function of DNS. A describes the basic function of a router, which is a device that directs traffic on a network. C refers to encryption services, which is not the primary function of DNS. D suggests that DNS is a protocol for remote device control, which is incorrect.
