http: protocol and www subdomain
The domain name system allows names to be assigned to Internet resources and users independent of the physical location of the resource or user.  This is beneficial because a domain name is easier to remember than an IP address, which is a series of numbers.  Even naive computer users can easily remember a URL, without having to understand how a computer locates it.
