Question

question: 1
what is the function of the domain name system (dns)?

• to sell website names to web developers
• to assign a unique domain name to every computer
• to make sure that each ip address has only one corresponding domain name
• to translate domain names into ip addresses

Explanation:

• The first option is incorrect because DNS does not sell website names.
• The second option is incorrect as DNS does not assign domain names to computers; it resolves domain names to IPs.
• The third option is incorrect because multiple domain names can map to one IP address (e.g., for load - balancing or shared hosting).
• The fourth option is correct. The main function of DNS is to translate human - readable domain names (like www.example.com) into IP addresses (like 192.168.1.1) that computers use to communicate over the internet.

Answer:

D. To translate domain names into IP addresses
