Which protocol is used to transfer web pages from a server to a client device?

The protocol used to transfer web pages from a server to a client device is called HTTP (Hypertext Transfer Protocol). Here are the steps explaining how it works:

1. A user enters a URL into a browser on the client device. This URL specifies the server where the web page is stored.

2. The browser sends an HTTP request to the server. This request includes the method (such as GET, POST, etc.), the URL, and other information about the client device.

3. The server receives the HTTP request and processes it. If the requested web page exists and the client device has the necessary permissions, the server sends an HTTP response back to the client device. This response includes the web page content and a status code indicating the result of the request.

4. The browser on the client device receives the HTTP response and displays the web page content to the user.

This process repeats each time a user requests a new web page or refreshes a current one. HTTP is a stateless protocol, meaning each request is processed independently without any knowledge of previous requests.
