What Is HTTP Protocol? A Comprehensive Guide for Beginners

If you’ve ever browsed the web, you’ve used HTTP—even if you didn’t realize it. But what is HTTP protocol exactly? In simple terms, it’s the foundation of data communication on the World Wide Web.

Understanding the Basics of HTTP

HTTP, or Hypertext Transfer Protocol, is an application-layer protocol used for transmitting hypermedia documents, such as HTML. It follows a client-server model where your browser (the client) requests resources from a web server.

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, which includes the requested content or an error message.

Key Features of HTTP Protocol

HTTP is stateless, meaning each request is independent. It also supports various methods like GET, POST, and PUT, enabling different types of interactions between clients and servers.

Common FAQs About HTTP
