What is DNS?
DNS, or Domain Name System, is the system that translates human-readable domain names like www.example.com into IP addresses that computers use to identify each other on the network. Without DNS, users would need to memorize IP addresses to visit websites or access online services. DNS operates as a distributed, hierarchical database spread across many servers around the world.
