= DNS =
The Domain Name System converts human-friendly domain names to IP addresses. Computers on the internet can only communicate with each other using IP addresses. But people aren't very good at remembering long strings of numbers (up to 12 digits for ipv4) or even longer strings of numbers and characters mixed (24 characters for ipv6).
Therefore DNS is a critical part of the internet infrastructure, and just about everyone who has a website needs to do something with it. Some all-inclusive web hosts offer domain name registration and automatically connect their hosting service to the domain registration, but that comes at the cost of any flexibility. From a technical point of view your domain name registration has nothing to do with the server that your DNS records are pointing to.
