NETGEAR Wireless Router Setup Manual

Glossary

August 2004

MAC address

The Media Access Control address is a unique 48-bit hardware address assigned to every network interface 
card. Usually written in the form 01:23:45:67:89:ab.

Mbps

Megabits per second.

Point-to-Point Protocol

PPP. A protocol allowing a computer using TCP/IP to connect directly to the Internet.

PPPoA

PPPoA. PPP over ATM is a protocol for connecting remote hosts to the Internet over an always-on 
connection by simulating a dial-up connection.

PPPoE

PPPoE. PPP over Ethernet is a protocol for connecting remote hosts to the Internet over an always-on 
connection by simulating a dial-up connection.

PPP over ATM

PPPoA. PPP over ATM is a protocol for connecting remote hosts to the Internet over an always-on 
connection by simulating a dial-up connection.

PPTP

Point-to-Point Tunneling Protocol. A method for establishing a virtual private network (VPN) by embedding 
Microsoft’s network protocol into Internet packets.

router

A device that forwards data between networks. An IP router forwards data based on IP source and 
destination addresses.

SSID

A Service Set Identification is a thirty-two character (maximum) alphanumeric key identifying a wireless 
local area network. For the wireless devices in a network to communicate with each other, all devices must 
be configured with the same SSID. 
This is typically the configuration parameter for a wireless PC card. It corresponds to the ESSID in the 
wireless Access Point and to the wireless network name. 

See also

 Wireless Network Name and ESSID.

Subnet Mask

A mask used to determine what subnet an IP address belongs to. Subnetting enables a network administrator 
to further divide an IP address into two or more subnets.
An IP address has two components, the network address and the host address. For example, consider the IP 
address 150.215.017.009. Assuming this is part of a Class B network, the first two numbers (150.215) 
represent the Class B network address, and the second two numbers (017.009) identify a particular host on 
this network.
