• URL stands for 'Uniform Resource Locator'. It serves as the unique global address that identifies and locates a specific resource (such as a webpage, image, document, or video) on the World Wide Web (WWW).
• A standard URL comprises distinct components:
• 1. Protocol/Scheme: Specifies the communication mechanism, such as `http://` or `https://`.
• 2. Domain Name / Host: The address of the web server (e.g., `www.example.com`).
• 3. Port: Optional networking port number (e.g., `:80` or `:443`).
• 4. Path: Specifies the exact location or route to the file on the server (e.g., `/folder/page.html`).
• 5. Query String: Optional parameters sent to the server (e.g., `?id=123`).
• Sir Tim Berners-Lee defined URLs in 1994 as part of the Uniform Resource Identifier (URI) specifications.
• Key Takeaway: A URL (Uniform Resource Locator) is the unique web address used to locate a specific resource on the WWW.
