URL

A URL, or Uniform Resource Locator, is a specific string of characters that identifies the location of a resource on the internet, such as a webpage or file, and provides a protocol for accessing it. In today's digital world, it's the key that unlocks the vast web, allowing users to navigate seamlessly from one site to another, though it must be carefully managed to avoid security risks like phishing. URLs have evolved to include elements like subdomains and query strings, making them essential for everything from simple browsing to complex API interactions.
