Web Browser And Their Working

Web browsers are applications used to access and exchange information on the internet. They fetch and display content from websites and transmit user inputs.
In 1990, Tim Berners-Lee introduced the World Wide Web (WWW) concept.
Modern browsers have core components:
- Request and Response: When you enter a URL, the browser sends a request to a server for the web page’s content.
  - This request travels through a network of servers, upon reaching the server, the request is received and processed.
  - The server then formulates a response containing the information (or data) required to construct the web page.
- Deconstructing the Response: The server’s response consists of HTML, CSS, and JavaScript files that define the webpage’s structure, style, and interactivity.
- Rendering: Browsers interpret HTML, apply CSS for style, and execute JavaScript for interactivity.
- Managing Data: Browsers use cookies and caching to enhance the user’s online experience, storing small data snippets and website information.
