Web Browser

A web browser is a software application that allows users to access websites on the Internet. It acts as an intermediary between the user and the Internet, transforming web addresses into visual, interactive content such as text, images, videos, and interactive elements.

Browsers are essential tools in the digital era, used daily for searching information, checking emails, online shopping, or interacting on social media.

How a Web Browser Works

  1. Entering a URL: The user types a web address (URL) into the address bar.
  2. Request to the Server: The browser sends a request to the server hosting the site using the HTTP or HTTPS protocol.
  3. Retrieving Data: The server responds by sending the necessary files (HTML, CSS, JavaScript, images, etc.).
  4. Rendering the Page: The browser interprets these files to display a visually understandable webpage.
