In computing, HTTP stands for Hypertext Transfer Protocol. It is the protocol used for transmitting hypertext over the internet.

HTTP is a fundamental protocol that allows web browsers and web servers to communicate with each other. Whenever you type a web address into your browser's address bar, it sends an HTTP request to the web server asking for the requested page. The server then responds with an HTTP response, which contains the requested web page along with other information, such as the status of the request.

HTTP is based on a client-server model, where the client (usually a web browser) makes requests, and the server responds with the requested data. This data can be in the form of HTML documents, images, videos, or any other type of file that can be displayed on a web page.

HTTP is a stateless protocol, meaning that each request and response are independent of each other. This allows for easy scalability and load balancing, as servers do not need to maintain any information about the client's previous requests.

HTTP operates on top of the TCP/IP protocol, which is the foundation of the internet. It uses port 80 for regular HTTP communication and port 443 for secure HTTPS communication. HTTPS, or Hypertext Transfer Protocol Secure, is an extension of HTTP that adds encryption and secure communication between the client and server.

As the backbone of the World Wide Web, HTTP has undergone several versions over the years. The most commonly used versions are HTTP/1.1 and HTTP/2. These newer versions have brought improvements in performance, efficiency, and security.

In conclusion, HTTP is the protocol that enables communication between web browsers and web servers. It allows for the transmission of hypertext, making it possible for us to access and view web pages on the internet. Understanding HTTP is crucial for anyone working with web development or using the internet on a daily basis.
