What is HTTP?

HTTP (HyperText Transfer Protocol) is an application layer protocol used for data transfer on the internet. It defines the rules for message exchange between a client (e.g., a browser) and a server, allowing the requesting and receiving of web pages, images, files, and other resources.

The protocol is based on a request-response model: the client sends an HTTP request, the server processes it, and returns an HTTP response with the required data and operation status.
