The Domain Name System (DNS) is a hierarchical naming system for computers and other devices on the Internet. It translates human-readable domain names like “google.

com” into numeric IP addresses. DNS is important for controlling the address space of the Internet, and for providing a way for users to find resources on the Web.

The DNS is decentralized, meaning that there is no single point of failure. This is important, as the DNS is used by billions of devices around the world.

If one DNS server were to go down, users would be unable to access the Internet.

DNS is also used for name resolution. This means that it is used to find the IP address for a particular domain name. For example, if I want to visit www.wikipedia.

com, my computer will look up the IP address for “wikipedia.com” in the DNS. My computer will then use that IP address to connect to the wikipedia.com server.
