Stateless protocol is a communications protocol in which no information is retained by either sender or receiver.

HTTP(Stateless | Application Layer | Uses TCP (80)) - No information is maintained. If in some case state maintenance is required then cookies are used. Now HTTPS is HTTP over a secure connection So it is also stateless.

FTP (Stateful | Application Layer | Uses TCP (20 and 21)) server that conducts an interactive session with the user. During the session, a user is provided a means to be authenticated and set various variables (working directory, transfer mode), all stored on the server as part of the user's state.

TCP (Stateful / Transport Layer) various information related to connection is maintained.

BGP (Stateful / Application Layer / Uses TCP ) and Finite state Automata is also used for maintaining state information.

POP3 (Stateful / Application Layer / Uses TCP(110))

In General if some authorization is required then stateful designed is used.
