A Uniform Resource Locator, the location of a resource on the internet. A URL is a type of URI (Uniform Resource Identifier), and consists of a scheme (in this context, HTTP or HTTPS), the name of a machine (sometimes also called the authority), and a path to a resource (for example, a file). For example, http://localhost/acubis10/index.html specifies the file named index.html from directory acubis10 on server machine localhost using the HTTP scheme. When this is typed into a web browser, the browser issues an HTTP GET request on this resource.
