What the connection software does
Once you have selected a service that will get you to the Internet, you must establish a phone link with
the service and configure your modem so that it can “speak” with the service’s computers. Like the
TCP/IP language spoken among computers on the Internet, your modem communicates with the
service’s computers in an industry-standard language, called Point-to-Point Protocol, or PPP. The data
sent by your computer in PPP is converted by the service’s computers into TCP/IP and then is sent out
over the Internet. When data arrives from the Internet, the translation process occurs in reverse.
When you use AICK, the Internet Dialer program establishes and configures the PPP connection
between your modem and the chosen ISP. A similar piece of software sets up the connection when you
use AOL. See the instructions that come with AICK and AOL for more information.
What you can do on the Internet
The complexity of the Internet makes it possible to communicate across it in a variety of ways,
including exchanging e-mail, teleconferencing, and retrieving files. Both AICK and AOL provide you
with software required for some of these forms of communication. (For more information, refer to the
manuals and online help for AICK and AOL.)
