Anonymous File Transfer Protocol (FTP)
A method for downloading public files using the File Transfer Protocol. Anonymous FTP is called anonymous because users do not provide credentials before accessing files from a particular server. In general, users enter the word “anonymous” when the host prompts for a username; anything can be entered for the password, such as the user’s email address or simply the word “guest. ” In many cases, an anonymous FTP site will not even prompt for a name and password.

A method of accessing electronic mail or bulletin board messages that are kept on a (possibly shared) mail server. IMAP permits a “client” email program to access remote message stores as if they were local. For example, email stored on an IMAP server can be manipulated from a desktop computer at home, a workstation at the office, and a notebook computer while traveling, without the need to transfer messages of files back and forth between these computers. IMAP can be regarded as the nextgeneration POP. A protocol used to transfer email messages from an email server to an email client.

Authentication protocol that allows PPP peers to authenticate one another. The remote router attempting to connect to the local router is required to send an authentication request. Unlike CHAP, PAP passes the password and hostname or username in the clear (unencrypted). PAP does not itself prevent unauthorized access, but merely identifies the remote end. The router or access server then determines if that user is allowed access. PAP is supported only on PPP lines. Compare with CHAP.
