FTP, or File Transfer Protocol, allows data files to be moved to and from two networked computers. The FTP client logs in to the FTP server.
Servers usually allow multiple clients to log in simultaneously.
Sending files from an FTP client to an FTP server is known as uploading . Obtaining files from a server onto a client machine is referred to as downloading . FTP allows files to be transferred in binary form, which means that a client and a server do not need to be running on the same operating system as long as the file can be read by both operating systems. To access an FTP server, the client must enter a user name and a password. When logging into an anonymous FTP site, users are often asked to provide their email addresses as the password.
