HTTP is a hypertext transfer protocol, the standard application protocol for data exchange on the World Wide Web. It defines the rules of interaction between a client (e.g., a web browser) and a server (storing web resources).

Main characteristics:

Stateless: Each request is processed independently of previous ones. The server does not store information about the client's state between requests.
Client-server architecture: The client initiates interaction by sending a request, and the server responds by providing the requested resource.

Example of a simple HTTP request:

GET /index.html HTTP/1.1
Host: www.example.com

Example of a simple HTTP response:

HTTP/1.1 200 OK
Content-Type: text/html
Content-Length: 1234

<!DOCTYPE html>
<html>
<body>
<h1>Hello, World!</h1>
</body>
</html>

HTTP is used for:

Loading web pages
File transfer
Interaction with web services (REST API)

There are different versions of the protocol, the most common ones are: HTTP/1.1 and HTTP/2.
