What is FTP?


 FTP stands for File Transfer Protocol. The protocol specifications were written by Abhay Bhushan and published as Request for Comments (RFC) 114 in April 1971.

 The File Transfer Protocol (FTP) is the standard network protocol used for the transfer of computer files between a client and server on a computer network. FTP is built on a client-server model architecture and uses separate control and data connections between the client and the server.
