DNS stands for Domain Name System. It is a hierarchical decentralized naming system for the internet that translates domain names (such as google.com) into IP addresses (such as 216.58.194.174) that computers can understand. DNS servers are responsible for maintaining a database of domain names and their corresponding IP addresses, and they facilitate the communication between different devices on the internet by allowing them to locate each other using domain names. DNS is a critical component of the internet infrastructure, and without it, users would have to remember and enter numerical IP addresses to access any website or service.
