What is an Internet Service Provider?

SLIP/PPP

In this option, the user also uses a modem to connect to a remote computer (called a SLIP server) at the ISP. However, in a SLIP/PPP account, the user's computer has both SLIP/PPP and TCP/IP software installed directly on it. This allows the user to choose whatever client programs (web browsers, ftp client, telnet client, etc.) he or she desires.
