FTP is used to transfer data from one computer to another over the Internet, or through a network.
FTP is a commonly used protocol for exchanging files from one computer to another over the Internet or any network that supports the TCP/IP protocol.
There are two computers involved in an FTP file transfer: a server and a client. The FTP server listens for connection requests from other computers. The FTP client initiates a connection to the server. Once connected, the client can do a number of file manipulation operations such as uploading files to the server, download files from the server, rename or delete files on the server and so on.
