What is DNS?
The Domain Name System (DNS) is like the internet's phonebook. It translates human-readable domain names, like "google.com," into IP addresses, like "172.217.160.142," which computers use to identify each other on the network. Without DNS, we'd have to remember and type in long strings of numbers to access websites, making the internet much less user-friendly.
