What is a URL commonly used for?

A URL, or Uniform Resource Locator, is primarily recognized as a standardized address that allows users to access specific resources on the internet. It serves as a pathway that directs browsers to locate and retrieve various types of content, such as web pages, images, videos, and files.

When a user enters a URL into a web browser, the browser utilizes the URL to navigate directly to the intended resource hosted on a server. This functionality is fundamental to how the internet is structured and operated, permitting seamless access to a multitude of information and services across the web.

The other options listed relate to different concepts: storing web content refers to server-side capabilities, filtering web traffic pertains to network security measures, and creating website designs involves web development skills. While these are all important aspects of the web ecosystem, they do not capture the primary purpose of what a URL is designed for.
