File Transfer Protocol (FTP)

See Also: Trivial File Transfer Protocol (TFTP)

A widely used Transmission Control Protocol/Internet Protocol (TCP/IP) protocol for transferring files from one machine to another. Internet users may use FTP applications to log in to FTP servers and download files. No restrictions are placed on file contents; they may contain text or binary data. Files may be protected from unauthorized access using authentication control, or they can be made public with anonymous FTP, which doesn't require a login name or password.
