What is DNS?

DNS, or Domain Name System, is a hierarchical naming system that functions like a phonebook for the internet by translating human-readable domain names, such as www.example.com, into numerical IP addresses that computers use to identify each other on a network. When you enter a web address into a browser, the system queries various servers to locate the specific IP address associated with that domain, allowing your device to establish a connection with the correct server. This process eliminates the need for users to memorize complex strings of numbers, ensuring that network communication remains user-friendly and efficient.
