A Uniform Resource Locator (URL) is a specific address used to access resources on the internet. It provides a way to locate a webpage, image, or file by specifying its location on a server. A typical URL consists of several parts, including the protocol (like HTTP or HTTPS), the domain name (such as example.com), and sometimes a path to a specific file or page. URLs are essential for navigating the web, as they allow users to enter addresses in a browser to reach desired content. Each URL is unique, ensuring that users can find the exact resource they are looking for without confusion.
