A method for downloading public files using the File Transfer Protocol (FTP). Anonymous FTP is called anonymous because you don’t need to identify yourself before accessing files. In general, you enter the word anonymous or ftp when the host prompts you for a username; you can enter anything for the password, such as your e-mail address or simply the word “guest”. In many cases, when you access an anonymous FTP site, you won’t even be prompted for your name and password.
You can use the Archiesystem to obtain a list of anonymous FTP sites and files available on each site.
Many FTP sites are protected. Unlike anonymous FTP sites, these restricted FTP sites can only be accessed by individuals who enter a valid username and password.
