HTTP and the Request-Response Model
HyperText Transfer Protocol (HTTP) defines the standard rules that web browsers and servers use to request and exchange web pages and resources across a network.
HTTP follows a straightforward client-server request-response pattern. A client, such as a web browser, initiates communication by sending a request (such as a request to retrieve a home page), and the web server returns the requested HTML, images, and associated files in its response.
Because HTTP requires accurate and complete data delivery, it runs on top of TCP, which provides reliable, ordered transmission. Web servers handling standard HTTP traffic typically listen on port 80.
