URL - MDN Web Docs Glossary: Definitions of Web-related terms 编辑

Uniform Resource Locator (URL) is a text string that specifies where a resource (such as a web page, image, or video) can be found on the Internet.

In the context of HTTP, URLs are called "Web address" or "link". Your browser displays URLs in its address bar, for example: https://developer.mozilla.org Some browsers display only the part of a URL after the "//", that is, the Domain name.

URLs can also be used for file transfer (FTP) , emails (SMTP), and other applications.
