Uniform Resource Locator

Uniform Resource Locator (URL)

Definition:
A URL (Uniform Resource Locator) is the web address used to locate a specific resource on the internet. It directs users and browsers to websites, files, images, videos, or other online resources. URLs are composed of a combination of letters, numbers, and sometimes symbols, but certain characters, like brackets and braces, are considered unsafe and can cause issues across different browsers.

How Does It Work?

1. Structure: A URL typically consists of the following components:
   • Protocol: Defines how the resource is accessed (e.g., http:// or https://).
   • Domain Name: Specifies the website’s name (e.g., www.example.com).
   • Path: Points to a specific resource within the website (e.g., /products/item).
   • Parameters (Optional): Additional data for specific queries (e.g., ?id=123).
   • Fragment (Optional): Points to a specific section on a page (e.g., #section1).
2. Functionality:
   • When a user enters a URL in a browser, the browser sends a request to the server hosting the resource.
   • The server processes the request and responds by sending the desired content to the browser.
   • The browser renders the resource (e.g., a webpage, image, or video) for the user.
