Users usually use user programs like ftp.exe. User programs have a user interface (generally a command line) that allow users to input user commands. The most fundamental function of a user program is converting a user command to an FTP command that is transmitted over a network. The FTP command always contains a keyword (for example, USER). This keyword can be followed by parameters separated by a space. The command is terminated with the CR (carriage return) and LF (new line) characters. FTP commands are always in ASCII.
