Domain names (often simply called domains) are easy-to-remember names associated with particular IP addresses. For instance, the domain name example.com might translate to 198.102.434.8. This makes it much easier to remember a website’s name Uniform Resource Locator (URL).
Examples of domain names are google.com and wikipedia.org. Owners of these domain names can create different subdomains such as http://www.google.com, docs.google.com, http://www.wikipedia.org, and en.wikipedia.org.
