Domain name
It is common to hear people say, “Just jump to: navigation and search – and you have a domain name”. The term domain name has multiple meanings and references and all of them are inter-related. It is basically a name that helps to identify a computer or many computers. It is an internet tool that helps navigate via names that appear as components of web site URLs. The domain name is also called a host name. The domain name is a product or service provided to the end users by domain name registrars.
Since the registrars provide the service to the customers, the names are often also referred to as registered domain names. There are names also used for other purposes within the domain name system or the DNS. There could be a special name to follow the @ sign in an e mail address or there could be domain names of the top level like.com, or even names used by the VoIP or Session Initiation Protocol. These are also sometimes colloquially and erroneously referred to as web addresses.
