Glossary

Point of Presence (POP)

In Internet terms, the physical site that contains an ISP’s network equipment. Remote users dial into the POP, authenticate against the ISP’s customer database, and then gain access to the Internet. ISPs typically have POPs scattered throughout their service area, so that can customers can dial a local phone call and avoid paying long- distance charges when accessing the Internet.

Point-to-Point Protocol (PPP)

The Internet standard for sending network traffic over serial lines, such as dial-up phone lines. Unlike its predecessor SLIP (Serial Line Internet Protocol), PPP provides error detection and compression capabilities.

Point-to-Point Tunneling Protocol (PPTP)

A network protocol for linking remote locations over the Internet rather than over costly long-distance or leased lines. To accomplish this, PPTP encapsulates other network protocols (such as TCP/IP, IPX, and NetBEUI) and uses encryption to secure the data sent over the Internet. PPTP was developed jointly by Microsoft and U.S. Robotics (3Com).

PPPoE

The Point-to-Point over Ethernet protocol provides a connection to the Internet through a DSL provider. It is also identified as PPPoE.
