File Transfer Protocol (FTP) is the protocol that actually lets us transfer files, and it can accomplish this between any two machines using it. But FTP isn’t just a protocol; it’s also a program. Operating as a protocol, FTP is used by applications. As a program, it’s employed by users to perform file tasks by hand. FTP also allows for access to both directories and files and an accomplish certain types of directory operations, such as relocating into different ones. FTP teams up with Telnet to transparently log you into the FTP server and then provides for the transfer of files.
Accessing a host through FTP is only the first step, though. Users must then be subjected to an authentication login that’s probably secured with passwords and usernames implemented by system administrators to restrict access. But you can get around this somewhat by adopting the username “anonymous”—though what you’ll gain access to will be limited.
Even when employed by users manually as a program, FTP’s functions are limited to listing and manipulating directories, typing file contents, and copying files between hosts. It can’t Execute remote files as programs.
