The Internet is a connected set of networks including the nationwide ARPAnet,
the Stanford Ethernet, and local networks at a variety of sites around the
country and in a few foreign countries.  Computers on the Internet, called
"hosts", use a common protocol that makes the actual means of connection
transparent to users.

SU-AI is connected to the Internet through both the ARPAnet and the Stanford
Ethernet.  Internet service is available to all users.  The basic services
available are:

    TELNET	Log in as a user on another host.
    FTP		Send and retrieve files to and from other hosts.
    MAIL	Send and receive text messages from users at other hosts.
