Moreover, a data port & a command port, & port 20 are a data-port for file transfer between the server & the client data flow. Port 21 is used as a command port and it’s used in transmitting control flow & accept associated FTP parameters and commands issued by the client. Both the receiver & the sender needs to have authentic access to the FTP server.

Proprietary: Here information transfer happens using every native format that’s well-matched between the receiver and the sender.
EBCDIC: Here plain text information is transferred using the EBCDIC character set.
-
Modes of Transmission
Information can be moved in three modes:
Block Mode: Information is broken to blocks through FTP using a byte count, header & information before it’s sent in TCP.
Stream-Mode: FTP transfers information in a constant stream, & TCP manages transfer.
Compressed-Mode: Information is compacted before it’s transmitted.
