Domain Name System (DNS) is a hierarchical naming system for computers, services, or other resources connected to the Internet or a private network. It translates human-readable domain names like "google.com" into machine-readable IP addresses like "172.217.0.142". DNS is an essential component of the internet as it allows users to access websites and other online resources by name rather than by IP address. DNS works by using a distributed database of DNS records, which are stored on DNS servers. When a user enters a domain name into a web browser, the browser sends a DNS query to a DNS resolver, which is a server that translates domain names into IP addresses. The resolver then queries the DNS database to find the IP address associated with the domain name and returns it to the browser. The browser then uses the IP address to connect to the website. DNS is a critical part of the internet and without it, users would not be able to easily access websites and other online resources.
