What is HTTP Protocol? A Comprehensive Guide

Have you ever wondered how your browser loads a webpage when you click a link? The answer lies in the HTTP protocol. In this guide, we’ll explore what HTTP is, how it works, and why it’s essential for the web.

Understanding HTTP Protocol

HTTP, or Hypertext Transfer Protocol, is the foundation of data communication on the World Wide Web. It enables clients (like browsers) to request and receive resources such as HTML pages, images, and videos from servers.

How HTTP Works: Request and Response

When you enter a URL, your browser sends an HTTP request to the server. The server processes this and returns an HTTP response with the requested data. This client-server model is stateless, meaning each request is independent.

Key Features of HTTP

HTTP is text-based, extensible, and supports various methods like GET, POST, and PUT. It also works alongside protocols like TCP/IP to ensure reliable data transfer.
