The protocol dealing with the transfer of hypertext between two or more computers is

HTTP is the protocol that governs the transfer of hypertext pages between two or more computers.

HTML is the markup language for writing those pages, not the protocol that moves them.

FTP transfers general files rather than serving hypertext to browsers.

TCP reliably carries the underlying data but does not itself define hypertext transfer.

HTTP works as a request-response exchange between a client and a web server.

It is stateless, so each request is handled independently of the last.
