 * File Transfer Protocol ** (** FTP **) is a type of protocol used to copy a file from one host to another over TCP . FTP is built on a client-server model and uses separate control and data connections between the client and server. It's a port number 20 or 21. Like the Hypertext Transfer Protocol (HTTP), which transfers displayable Web pages and related files, and the Simple Mail Transfer Protocol (SMTP), which transfers e-mail, FTP is an application protocol that uses the Internet's TCP/IP protocols. FTP is commonly used to transfer Web page files from their creator to the computer that acts as their server for everyone on the Internet. It's also commonly used to download programs and other files to your computer from other servers.
