DNS (Domain Name System) is a system that translates human-readable domain names (like www.example.com) into IP addresses, allowing browsers to locate and load websites. DNS acts as the internet's address book.
Important Key Points:
1. IP Translation: Converts domain names to IP addresses for easy access.
2. Internet Navigation: DNS simplifies accessing websites by using domain names instead of numerical IP addresses.
3. Hierarchical Structure: DNS operates in a hierarchical format, making it efficient for large-scale use.

· Domain Number System: Incorrect, as DNS focuses on name resolution, not number systems.
· Document Name System: Irrelevant to the domain name and IP address conversion function of DNS.
