Telnet : Remote login works on port number 23.Allows you to establish remote session on the server. Does not support Graphical User Interface (GUI) interface but supports only through commands, i:e; command line utility. And provides very little security.FTP : File Transfer Protocol works on port number 21.FTP works on Application Layer Protocol and is used to transfer files securely between TCP/IP systems, providing file security. More secured because of user authentication and user logons and uses two types of connections (Data and Control Connection). FTP uses many commands and FTP uses TCP,i:e; 20 port number for data connection and 21 for control connection.HTTP : Hypertext Transfer Protocol works on port number 80. HTTP is used to transfer hypertext files across internet. Requires an HTTP client program on one end and HTTP server program on other end.RPC : Remote Procedure Calls works on port number 135.RPC is used for remote administration. Its function is to forward application function call to a remote system over the network. It can be used in IPv6 or IPng (IP version 6 or IP next generation which uses 128 - bit IP addressing).

Port is registered with IANA for the application = Official
Port is not registered with IANA for the application = UnOfficial

Telnet = port - 23(Official)

FTP = port - 20(Data Tx), 21(Command), 22(SSH, Secured file Transfers and port forwarding)

HTTP = port - 80(Official)

RPC = port 530 (Official), 135(Unofficial-Microsoft EPMAP (End Point Mapper), also known as DCE/RPC Locator service, used to remotely manage services including DHCP server, DNS server and WINS. Also used by DCOM)
