File Transfer Protocol

File Transfer Protocol or FTP, in computer communications, on the Internet and other networks, a method of transferring files from one computer to another. The protocol is a set of rules that ensures a file is transmitted properly to the receiving computer. A computer that stores files that can be retrieved using FTP is called an FTP site or FTP server. FTP is part of the Transmission Control Protocol/Internet Protocol (TCP/IP), the system that enables different types of computers and networks on the Internet to communicate.
