A Uniform Resource Locator (URL) is the address used to access resources on the internet. URLs specify the location of a web page or file on a server and how it can be retrieved. For example, a URL like "https://www.example.com" consists of several parts: the protocol (HTTPS), the domain name (example.com), and optionally a path to a specific page or file. URLs are essential to web browsing, as they provide a user-friendly way to navigate the vast amount of information available on the internet. Every web page, image, or downloadable file online has its unique URL.
