Glossary of Internet Terms
- Acceptable Use Policy
Internet connectivity providers may restrict the way in which their networks
are used. The Acceptable Use Policy defines the rules for using the network.
See IP Address or E-Mail Address.
- Anonymous FTP
Some FTP sites allow users to use the word "anonymous" as a User ID and their
e-mail addresses or "guest" as a Password when they log in. This allows the
users to bypass local security and gain limited access to download public
files on the FTP site. This type of access is not available on all FTP sites,
and may be restricted to a maximum number of anonymous users on others. See
File Transfer Protocol.
A software tool for finding files on the Internet. Some Archie clients can

not communicate. For example, a company network's internal e-mail format might
be translated into an Internet e-mail format for outside communications. The
translation mechanism is a gateway.
