Which programs
are allowed to exchange information from the Internet? Microsoft Office
Outlook uses Simple Mail Transfer Protocol (SMTP) to synchronize your
email with your server.
Microsoft
FrontPage uses a different Port to update your web pages with File
Transfer Protocol (FTP).
Remote
Administration and Remote Assistance use a different protocol to enable
you to log onto someone else's machine--across the city or on the other
side of the Internet--and get permission to manage changes on their
system.
