Why does ftp use two standard ports, Computer Engineering

Assignment Help:

Why does FTP use two standard ports whereas other protocols, in general use only one port? Justify.

File transfer protocol uses a control connection just to send commands and receive responses. While this transfers a file, it does not send the data across the control connection. As an alternative, the client and server establish a separate data connection for all file transfer, utilize this to send one file, and after that close the connection. If the user requests other transfer, the client and server set up a new data connection. To ignore conflict in between data and control connections, FTP uses a various port number for each.
