**HTTP: The Foundation of Web Communication**
**HTTP**, or **Hypertext Transfer Protocol**, is the fundamental set of rules that allows web browsers and web servers to communicate with each other. When you type a website address or click a link, your browser sends an HTTP request to the server hosting that website. The server then processes this request and sends an HTTP response back to your browser, which contains the web page content (like text, images, and videos) that you see. This continuous exchange of **HTTP messages** is what makes the **internet** navigable, enabling you to browse web pages, submit forms, and interact with online applications seamlessly. Understanding **how HTTP works** is key to comprehending the basic architecture of the World Wide Web.
