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. When referring to an Internet address or name a domain or domain name is the location of a website. For example, the domain name "google.com" points to the IP address "216.58.216.164". Generally, it's easier to remember a name rather than a long string of numbers.
