How is data transferred between the user and the site?

Question

Browsers

Now, while reading the book, I understood how a connection is established between the client and the server, the so-called. triple handshake, etc. p.
And how is the further amount of data between the client and the server? Are Get and Post requests still going between them? Or are there already some other technologies for transmission?
