DNS is a Domain Name System (DNS) that allows computers on the Internet to resolve domain names to IP addresses. It is a hierarchical system in which each domain name is divided into smaller subdomains. For example, the domain name “google.com” is divided into the subdomains “google.com, www.google.com, info.

com, and www.youtube.com”. When a user types in the domain name “google.com” into a web browser, the DNS system will look up the IP address for “google.com” in its databases and return the corresponding response from a server on the Internet.
