multicast group. All hosts conforming to level 2 of the IP multicasting
specification require IGMP.
IEEE It is the Institute of Electrical and Electronic Engineers. The IEEE is a
professional technical body promoting the development and
application of technology.
IP Address At the moment, IP address is a 32-bit binary digit that defines each
sender or receiver of information across an IP network.
IPSec Internet Protocol Security. It is a suite of protocols used to implement
secure exchange of packets at the IP layer.
ISP Internet Service Provider. It is a company that provides individuals or
corporations with Internet access and other related services.
LAN Local Area Network is a group of computers and devices sharing a
common communication medium within a small geographical area.
Latency Latency is a time-delay.
MAC Address MAC is the abbreviation for Media Access Control. The MAC address is
a unique number assigned by the manufacturer to any Ethernet
networking device, such as a network adapter or router. It allows a
network to identify the hardware. Unlike IP addresses, this number is
permanent and is therefore a valuable identifier.
Mbps Mega bits per second. It is a unit of measurement for data transmission
indicating a million bits per second.
Multicasting To transmit a single message to a select group of network recipients.
NAT Network Address Translations multiplexes multiple private IP addresses
for the LAN to a single public IP address on the Internet.
OFDM Orthogonal Frequency Division Multiplexing. It is a modulation scheme
employed by the IEEE 802.11g standard, which combines numerous
signals of different frequencies to form a single signal for transmission
over a medium.
Packet Filtering This is a means of discarding unwanted network traffic based on its
originating IP addresses or the type of packet/data transmitted.
Parallel Broadband This exclusive feature enables the connection of multiple broadband
routers to a single network.
Ping Packet Internet Groper is a utility used to determine whether a
particular IP address is available online. It works by sending out a
packet and waiting for a response from the recipient.
PPPoE Point-to-Point Protocol over Ethernet is a method for the encapsulation
of PPP packets over Ethernet frames.
