Is FTP traffic UDP or TCP?
TCP
FTP is a TCP based service exclusively. There is no UDP component to FTP. FTP is an unusual service in that it utilizes two ports, a ‘data’ port and a ‘command’ port (also known as the control port). Traditionally these are port 21 for the command port and port 20 for the data port.
Why does FTP use two ports?
FTP is an old protocol. That’s really the only reason. The designers thought that the amount of data flowing over the data port would make it so that they couldn’t send control commands in a timely manner, so they did it as two ports.

FTP clients will then connect to the FTP server on port 21 and initiate a conversation. This main connection is called the Control Connection or Command Connection.
