URL is an acronym for Uniform Resource Locator.
A URL is a way to specify a resource, such as a file or a service, on the internet. In what is by far the most common usage, a URL is simply the full web address of a webpage. For example, this page is identified by the URL
A URL is made up of several components.
- Protocol or “scheme”: the “language” used to exchange data for this specific type of resource.
- Server or host: the computer (or computers) on the network that provide the resource.
- Location or path: the location on the server containing the resource.
- Name: the name of the resource to be accessed. (Technically considered part of the location.)
- Parameters or query: additional information used to customise the resource, or to be included with the request for other purposes.
- Anchor or fragment: additional information that indicates which portion of the resource should be accessed.
Many of the components are optional.
The most recognizable indicator of something being a URL is the “://” between the protocol and server. Using the terms above in brackets, a URL is constructed as follows:
<protocol>://<server>/<location>/<name>?<parameters>#<anchor>« Back to Glossary Index
