FTP

FTP or File Transfer Protocol is used to transfer data from one computer to another over the Internet, or through a network.

Specifically, FTP is a commonly used protocol for exchanging files over any TCP/IP based network to manipulate files on another computer on that network regardless of which operating systems are involved (if the computers permit FTP access). There are many existing FTP client and server programs. FTP servers can be set up anywhere between game servers, voice servers, internet hosts, and other physical servers.

The default TCP port for FTP is 22.
