TCP/IP, PPP, & Internet Connect

Your computer accesses the Internet via a TCP/IP connection. TCP/IP is a standard Internet protocol, or set of rules, for exchanging information.

A TCP/IP connection works like a pipeline. Once established, Internet applications—such as your Web browser and e-mail program—reach through the TCP/IP pipeline to get the information they need. When the information has been sent or received, it stops flowing through the pipeline. But the pipeline is not disconnected.
