individuals or companies. The most common TLDs are:
??‘ com for commercial sites

haxe is a first - level domain. It is an arbitrary name acquired for a limited time by an individual
or a company. The domain subscription is usually renewed on a per - year base.
www is a second - level domain. A first - level domain owner can create as many second - level
domains as desired; some hosting companies cover a price for second - level domain related to
technical costs. The www second - level domain is nowadays a de facto standard to locate the main
entry point for most existing first - level domains. The presence of an SLD is optional.
http is the protocol used to connect to the resource specified by the address.
A web server is usually configured so that its root address points to the content of a physical directory
on the hosting machine.
