     Answers Explanation & Hints: An FTP client is an application that runs on a computer used to push and pull files from a server running an FTP daemon. To transfer files, FTP requires two connections between the client and the server: one for commands and replies and another for the actual file transfer. The client establishes the first connection to the server for control traffic and the second connection for the actual file transfer. This connection is created every time there is a file to be transferred. The client can download a file from or upload a file to the server.
