FTP - File Transfer Protocol

FTP - File Transfer Protocol


File Transfer Protocol (FTP) basically used for transfer files between client and server. FTP is built on the client-server model architecture, using separate controls and data connections between the client and the server.

FTP users can authenticate themselves with a username and password but can connect anonymously if the server is configured to allow it. FTP is secured with FTPS or SFTP (SSH File Transfer Protocol).

How Does FTP Work?

FTP was developed in the 1970s to support file sharing on computer networks. The protocol follows the client-server model of communication. To transfer files with File Transfer Protocol, a user runs an FTP client program and initiates a connection to a remote computer running FTP server software. After the connection is established, the client can choose to send and/or receive files.

The original "File Transfer Protocol" clients were command-line programs for Unix OS; Unix users ran 'ftp' command-line client programs to connect to File Transfer Protocol servers.

A file transfer protocol server listens on TCP port 21 for incoming connection requests from FTP clients. The server uses this port to control the connection and opens a separate port to transfer file data.

For any FTP site, clients identify the File Transfer Protocol server either by its IP address (such as - 192.168.0.1) or by its hostname (such as - ftp.about.com).

FTP supports two modes of data transmission: plain text (ASCII), and binary. You set the mode in the File Transfer Protocol client. A common error when using File Transfer Protocol is attempting to transfer a binary file (such as a software or music file) while in text mode, causing the transferred file to be unusable.

Alternatives to File Transfer Protocol

Peer-to-peer (P2P) file-sharing systems like BitTorrent offer more advanced and secure forms of file sharing than FTP technology offers. These plus modern cloud-based file-sharing systems like Box and Dropbox have largely eliminated the need for File Transfer Protocol on the Internet.
