Most commonly used to find resources on the World Wide Web, but much more general in capability, a Uniform Resource Locator (URL). Their syntax is:
<scheme>:<scheme-specific-part>
A URL contains the name of the scheme being used (<scheme>) followed by a colon and then a string (the <scheme-specific-part>) whose interpretation depends on the scheme. [1]
Representative schemes
Primary WWW usage
Most often, URLs use a scheme of http to refer to the Hypertext Transfer Protocol as the scheme, and a fully qualified Domain Name System (DNS) name as the locator.
This commonly refers to a link on the World Wide Web. URLs usually start with https://, e.g. this page's URL is https://citizendium.org/wiki/Uniform_Resource_Locator. In this example, the citizendium.org is a DNS name.
Direct IP protocol request
