Domain Name Server (DNS) is a system that includes a database of the public IP addresses with website names. It acts as a resolver that converts domain names to IP addresses. If a user wants to open Google on the chrome page, DNS will resolve the name Google and check for the IP address in the cache memory. Based on the IP address, the computer gets connected with the web server and retrieves the web page to perform various actions on the Google web page.

Like humans communicate with each other, computers also do communicate with each other, but not by the names; they have their unique numbers, such as IP addresses over a network. Humans are customized to address by the names instead of numbers to identify a person or a site. To communicate between computers and humans, networking engineers developed a Domain Name Server (DNS). This blog is curated about how DNS works. But before that, What is DNS?
