A Domain Name is a unique string of alphanumeric characters in a special format that represents an IP Address. An example of a domain is “google.com”
Domain names are managed by the ICANN although each extension is managed by a different company/country or organization and the domain itself would be sold by domain registrars.

A domain name is separated into 4 parts called the prefix, subdomain, domain, and suffix. The only part that is optional is the subdomain. A subdomain a domain under the main domain. (Ex: http://drive.google.com)
