URL
A URL, or Uniform Resource Locator, is a unique web address that tells a browser where to find a specific resource on the internet, like a webpage, image, or video. It acts like a street address for online content, containing information about how to access it and what you're looking for. URLs are what you type into a browser's address bar or click on as a link.
Unique identifier: A URL is a text string that provides a specific location for a resource online.
Purpose: It makes it possible to retrieve published resources by guiding a web browser to the correct location.
Examples: You can find URLs for web pages, images, videos, audio files, and documents.
How it's used: You see URLs in your browser's address bar and click on them as links in emails or on other web pages.
