File transfer protocol (ftp), which was one of the first tools on the internet, allows users to move files, such as text, graphics, sound, and so on, from one computer to another. It is a command that activates a type of client-server relationship. Fip works as follows: The user first uses the software on his or her machine (or service provider), called the client, to gain access to remote machine, called the server. The user’s client program communicates with a program on the remote computer, to either upload, or send, files to the remote computer or download (receive) certain requested files from it.
