👉 URLs (Uniform Resource Locators) are standardized web addresses that uniquely identify resources on the internet. They follow a specific format consisting of a protocol (like HTTP or HTTPS), a domain name, and optional path segments. For example, "https://www.example.com/page123" is a URL where "www.example.com" is the domain name, and "/page123" specifies the exact resource within that domain. URLs are crucial for navigating web pages, accessing files, and linking between different resources on the internet. They ensure that users can reliably locate and retrieve information from various websites, making them a fundamental component of web communication and data exchange.
