The File Transfer Protocol (FTP) is used to transfer files between two computers over a network and the internet.
FTP is a standard network protocol used for the transfer of computer files from a server to a client using the client–server model on a computer network. FTP's default network port numbers are 20 and 21.
FTPS, also known as FTPES, FTP-SSL, S-FTP, and FTP Secure, is an extension to the commonly used FTP that adds support for the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) cryptographic protocols.
