A domain name is the unique name of a computer on the Internet that distinguishes it from the rest.
Every website on the Internet is hosted on a computer (server). Each server has a unique IP address which is nothing but a unique set of numbers, such as "207.142.131.235". To access a particular website, one can specify its IP address in an appropriate application, such as a web browser; however because it is difficult to remember numbers, each IP address is associated with a fully qualified host name (a domain name), such as "www.BambooWeb.org".
Translating numeric addresses to alphabetical ones, domain names allow Internet users to localize and visit websites.
