What is a Domain Name?
A domain name is a unique name for a web site, like w3schools.com.
Domain names must be registered. When domain names are registered, they are added to a large domain name register. In addition, information about the web site, including the IP address, is stored on a DNS server.
DNS stands for Domain Name System. A DNS server is responsible for informing all other computers on the Internet about the domain name and the web site address.

Registering a Domain
Domains can be registered from domain name registration companies.
These companies provide interfaces to search for available domain names, and they offer a variety of domain name extensions that can be registered at the same time.
