In networking, what is the function of a DNS server?

Converts IP to MAC address
Converts domain names to IP addresses
Sends data to the next hop
Encrypts outgoing messages

Correct Answer: B. Converts domain names to IP addresses

Detailed Explanation

A DNS (Domain Name System) server is used to convert domain names into IP addresses. When you type a website name like google.com into your browser, the DNS server finds the correct IP address so your computer can connect to that website.

This process is called domain name resolution and it helps users access websites using easy-to-remember names instead of numeric IPs.

Other options:

IP to MAC: Done by ARP (Address Resolution Protocol)

Next hop: Handled by routers using routing tables

Encryption: Managed by security protocols like SSL/TLS
