Most ISPs provide dial-up connections supporting PPP because it is a fast and efficient protocol for using TCP/IP over serial lines. PPP is designed for two-way networking; TCP/IP provides the transport protocol for data.
PPP (Point to Point Protocol) uses several components on your system. The first is a daemon called pppd, which controls the use of PPP. The second is a driver called the high-level data link control (HDLC), which controls the flow of information between two machines. A third component of PPP is a routine called chat that dials the other end of the connection for you when you want it to.
