C Glossary

these two protocols, contact your ISP for an authentication script.

PPP

Short for Point-to-Point Protocol, a communications protocol for transmitting information over standard telephone lines between devices from different manufacturers.

PPPoE

Short for PPP over Ethernet, relying on two widely accepted standards, Ethernet and the Point-to-Point Protocol. It’s a communications protocol for transmitting information between devices from different manufacturers over an Ethernet.

PPTP

Short for Point to Point Tunneling Protocol, PPTP encapsulates the packet for transmission over the Internet. It is similar to creating a private “tunnel” over a large public network and has almost equal security to a private network without actually leasing a private line.

Protocol

An agreed format for transmitting, sending and receiving data between two devices.

Roaming

The ability for a wireless device moving from one access point’s range to another without losing the connection.

Router

An Internet device that routes requests for information to other routers until the information’s location is found and the data can be transmitted back to the origin of the request.

SPI

SPI is an acronym for Stateful Packet Inspection. The SPI engine examines not just the headers of the packet, but also the packet contents, it can then determine more about the packet than just its source and destination information. Moreover, stateful inspection firewalls also close off ports until a connection to the specific port is requested.

TCP/IP

Short for Transmission Control Protocol and Internet Protocol, the suite of communications protocols that enable hosts on the Internet to connect and exchange streams of data.

VPN

VPN is an acronym for Virtual Private Network. Via access control and encryption, VPN brings the same security to data transmission through the Internet as if it is being transmitted through a private network. It not only takes advantage of economies of scale but also ensures high level security while the packet is sent over the large public network.

Wide Area Network (WAN)

A system of LANs being connected by telephone lines and radio waves. Although
