A domain is a user-friendly naming system that allows people to easily navigate web servers and web pages. Rather than making people type in an IP address whenever they want to access a certain web page (like 126.96.36.199), websites are instead assigned easy-to-remember character strings, called domains.
A domain name is an identification string that defines a realm of administrative autonomy, authority or control within the Internet. Domain names are formed by the rules and procedures of the Domain Name System (DNS).
