NAT (Network Address Translation)
A network algorithm used by Routers to enables several PCs to share single IP address provided by the ISP.
The IP that a router gets from the ISP side is called Real IP, the IP assigned to PC under the NAT
environment is called Private IP.
Node
A network connection end point, typically a computer.
Packet
A unit of data sent over a network.
Passphrase
Used much like a password, a passphrase simplifies the WEP encryption process by automatically generating
the WEP encryption keys for the company products.
PoE (Power over Ethernet)
A standard to deliver both power and data through one single Ethernet cable (UTP/STP). It allows network
device to be installed far away from power ource. A PoE system typically compose of 2 main component: DC
Injector (Base Unit) and Splitter(Terminal Unit). The DC injector combines the power and data, and the splitter
separates the data and power back. A PoE Access Point or CPE has the splitter built-in to the device. The
IEEE 802.3af is a POE spec that uses 48 volt to deliver power up to 100 meter distance.
Port
This word has 2 different meaning for networking.
The hardware connection point on a computer or networking device used for plugging in a cable or an adapter.
The virtual connection point through which a computer uses a specific application on a server.
PPPoE
Point-to- Point Protocol over Ethernet. PPPoE relies on two widely accepted standards: PPP and Ethernet.
PPPoE is a specification for connecting the users on an Ethernet to the Internet through a common
broadband medium, such as a single DSL line, wireless device or cable modem.
