PPP (Point to Point Protocol) and SLIP (Serial Line Internet Protocol) are protocols that permit users to interactively connect to the Internet using an IP address. The connection takes place over serial links, such as regular telephone lines, using TCP/IP. Computers on each end of the serial link run TCP/IP-based networking software. Connecting to an Internet via an Internet Service Provider's (ISP) a host machine using a SLIP/PPP account permits users to bypass UNIX, and navigate the Web directly from Windows, using GUI-based Web browsers like Mosaic, Netscape, or ftp clients.
Before you can use your SLIP/PPP account, you'll need to add a SLIP/PPP daemon to your PC that makes and maintains the connection, as well as client software like Telnet, FTP, etc. The most commonly used SLIP/PPP daemon is WINSOCK. It's available via anonymous ftp at: ftp.trumpet.com.au (/winsock dir).
