Definition
The Domain Name System (DNS) is a hierarchical and decentralized naming system that translates human-readable domain names (like www.example.com) into IP addresses (like 192.0.2.1) that computers use to identify each other on the network.
Function
The main function of DNS is to facilitate the internet's ability to locate and connect to devices and services using easy-to-remember domain names instead of numerical IP addresses. This system allows users to access websites, send emails, and perform other networked activities seamlessly, without needing to remember complex numerical addresses. DNS also provides essential functions such as domain name registration and the management of domain name records.
