A URL (Uniform Resource Locator) is the address used to access specific pages or resources on the internet. It appears in your web browser’s address bar and typically starts with 'http://' or 'https://', followed by the website’s domain name and sometimes additional paths or parameters. URLs help browsers and other software locate and retrieve online content, making it possible for users to visit websites, download files, or access other online services. Every unique web page or resource has its own distinct URL, ensuring precise navigation across the internet.
