A protocol for communication between computers using TCP/IP, over standard telephone lines, ISDN, and other high-speed connections. PPP was developed by the Internet Engineering Task Force (IETF) and is defined with graphical fronts (like Mosaic and Netscape) in RFC 1171. It can be used to connect a computer to the Internet, for services such as the World Wide Web and e-mail. PPP is faster than SLIP, includes error detection and data compression; it can be used for router-to-router and host-to-network connections with both synchronous and asynchronous transmission. A Macintosh control panel, called "Config PPP", is opened by the user to establish a connection containing PPP instructions, such as port speed, modem string, telephone number, server identity, and the like. See SLIP, TCP/IP.
