The Uniform Resource Locator (URL) is a technical, Web-related term used in two distinct meanings:

  • in popular usage, it is a widespread synonym for Uniform Resource Identifier (URI) - many popular and technical texts will use the term "URL" when referring to URI;
  • in strict technical usage, it is a subset of URI specific to identifiers who are primarily locators.

The web page address that you type or paste in your browser is commonly called an URL.

Here is a typical URI dissected:

   http://example.com:992/animal/bird?species=seagull#wings
   \__/   \_________/ \_/\__________/ \_____________/ \___/
    |          |       |       |             |          |
  scheme      host    port    path         query     fragment
