PPP Connection

by Sarah Barnett

The PPP stands for Point-to-Point Protocol.  This is communication protocol used over serial lines to support Internet connectivity. To connect to the Internet via Serial Line Internet Protocol (SLIP) or Point to Point Protocol (PPP), you need to have TCP/IP software on your computer. When connected by SLIP/PPP, your computer actually becomes another node on the Internet. You can then run popular client software directly. This has an advantage over a shell account where you will have to double download in order to transfer a file by FTP because the data first goes to network and then to a local machine.

Necessary? Yes
I often have to check for IP account problems.  Mostly the problem is a duplicate number being used in the district.  I didn't know that this number had anything to do with running software.

PPP: PPP is short for Point to Point Protocol and is a data link protocol that provides dial-up access over serial lines. This allows a computer running TCP/IP to connect to the Internet over standard phone lines using a high speed modem. It can run on any full duplex lines. Since being developed in 1991, it has become popular for Internet access as well as a method for carrying higher level protocols. PPP provides a more stable connection between a computer  and the Internet than a SLIP connection and also offers error checking features unavailable with SLIP connections.
