URL (Uniform resource locator) is the pointer / locator of an Active Web Page. These URLs may also be refer to as domains or portals, which are links to navigate billions of webpages.

The URL is used to address a document for order data on the World Wide Web. When you click on a link in an HTML document, an underlying anchor points to a page ( a domain address) on the Web with attribute value like this:
W3schools

A full Web address follows these syntax rules:
Scheme://host.domain:port/path/filename
The scheme is defining the type of Internet service. The most common type is http.
The domain is defining the Internet domain name like w3schools.com.
The host is defining the domain host. If omitted, the default host for http is www.
The :port is defining the port number at the host. The port number is normally omitted. The default port number for http is 80.
The path is defining a path (a subdirectory) at the server. If the path is omitted, the resource (the document) must be located at the

root directory of the Website

.
The filename is defining the name of a document. The default filename might be default.asp, index.html or something else depending on the setting of the wed server.
