A URL, or Uniform Resource Locator, is the specific address used to access resources on the internet, such as web pages, images, or files. It acts as a reference that tells web browsers where to find a particular resource by specifying its location and the protocol to use (like HTTP or HTTPS). A typical URL includes components such as the protocol, domain name, and sometimes a path or query string, for example: https://www.example.com/page. URLs are essential for navigating and linking content across the web.
