FTP users may authenticate themselves using a clear-text sign-in protocol but can connect anonymously if the server is configured to allow it. The first FTP client applications were interactive command-line tools, implementing standard commands and syntax. Graphical user interface clients have since been developed for many of the popular desktop operating systems in use today. The original specification for the File Transfer Protocol was written by Abhay Bhushan and published as RFC 114 on 16 April 1971, before TCP and IP even existed. It...
