A domain name can be used for a website or email, this is what people type into a browser to find your website. My domain name is digicomhowto. Sometimes it can be quite difficult to find a domain name that hasn’t already been used.
On the Web, the domain name is that part of the Uniform Resource Locator(URL) that tells the domain name system (DNS) whether and where to forward a request for a Web page. A DNS enables websites to use names rather than difficult IP address that no one would remember.
The domain name is mapped to an IP address (which represents a physical point on the Internet).
