FTP provides a simple way to move files across the Internet by giving user

account and a password for authenticated users.

established user account and password on the system. In other word, a user

may log on as anonymous and use his e-mail address as the password.

communications protocol. As software, telnet is important to display text-only

information. Only primitive graphics can be displayed on a telnet application.

displaying text on the screen.

software is still necessary. Most universities (especially libraries) must be
