4. Glossary
Ad-Hoc Mode
An Ad-hoc integrated wireless LAN is a group of computers, each has a Wireless LAN
adapter, Connected as an independent wireless LAN. Ad hoc wireless LAN is applicable at
a departmental scale for a branch or SOHO operation.
BSS ID
A specific Ad hoc LAN is called a Basic Service Set (BSS). Computers in a BSS must be
configured with the same BSS ID.
DHCP (Dynamic Host Configuration Protocol)
DHCP is a protocol for dynamically assigning IP addresses to networked computers. With
DHCP, a computer can automatically be given a unique IP address each time it connects to
a network—making IP address management an easier task for network administrators.
When a computer logs on to the network, the DHCP server selects an IP address from a
master list and assigns it to the system.
DMZ Host (De-Militarized Zone Host)
DMZ is the portion of a private network that is visible through the network’s firewalls. DMZ
Host allows a local computer exposed to the Internet. Therefore, an incoming packet will be
checked by Firewall and NAT algorithms in the router then pass to the DMZ host when
packet is not sent by hacker and is not limited by Virtual Server list. Besides, there are
some IP protocols that do not have port number information. There is no way to use Virtual
Server setting to forward incoming packet. Thus, DMZ host is the way to forward such kind
of packets. If you try to enable DMZ host and setup Virtual Server, the precedence is Virtual
Server and then DMZ. For example, the incoming packet will be checked with Firewall rules,
Virtual Server rules and
then DMZ host.
DSSS (Direct-Sequencing Spread-Spectrum)
DSSS operate over the radio airwaves in the unlicensed ISM band (industrial, scientific,
medical). DSSS uses a radio transmitter to spread data packets over a fixed range of
frequency band.
Encryption
It’s a security method that applies a specific algorithm to data in order to alter the data
appearance and prevent other devices from reading the information.
Firewall
A firewall is a device that sits between your computer and the Internet that prevents
unauthorized access to or from your network. A firewall can be a computer using firewall
65
Download from Www.Somanuals.com. All Manuals Search And Download.
802.11g 4-Port Wireless LAN Broadband Router
software or a special piece of hardware built specifically to act as a firewall. In most
circumstances, a firewall is used to prevent unauthorized Internet users from accessing
private networks or corporate LAN’s and Intranets.
A firewall watches all of the information moving to and from your network and analyzes
each piece of data. Each piece of data is checked against a set of criteria that the
administrator configures. If any data does not meet the criteria, that data is blocked and
discarded. If the data meets the criteria, the data is passed through. This method is called
packet filtering.
A firewall can also run specific security functions based on the type of application or type of
port that is being used. For example, a firewall can be configured to work with an FTP or
Telnet server. Or a firewall can be configured to work with specific UDP or TCP ports to
allow certain applications or games to work properly over the Internet.
Firmware
Program that is inserted into programmable read-only memory (programmable read-only
memory), thus becoming a permanent part of a computing device.
Fragmentation Threshold Value
Indicates how much of the network resources are devoted to recovering packet errors. The
value should remain at its default setting of 2,432. If you experience high packet error rates,
you can decrease this value but it will likely decrease overall network performance. Only
minor modifications of this value are recommended.
Fragmentation
Breaking a packet into smaller units when transmitting over a network medium that cannot
support the original size of the packet.
IEEE
The Institute of Electrical and Electronics Engineers
IEEE 802.11b/g standard
The IEEE 802.11b/g Wireless LAN standards subcommittee formulates standards for the
industry. The objective is to enable wireless LAN hardware from different manufacturers to
communicate.
Infrastructure Mode
A client setting provides connectivity to an Access Point. As compared to Ad-Hoc mode
where PCs communicate directly with each other, clients set in Infrastructure mode all pass
data through a central Access Point. The Access Point not only mediates Wireless network
traffic in the immediate neighborhood but also pro-vides communication with the wired
network. An integrated wireless and wireless and wired LAN is called an Infrastructure

configuration. Infrastructure is applicable to enterprise scale for wireless access to central
database, or wireless application for mobile workers.
LAN (Local Area Network)
Local Area Networking (LAN) is the term used when connecting several computers
together over a small area such as a building or group of buildings. LAN’s can be
connected over large areas. A collection of LAN’s connected over a large area is called a
Wide Area Network (WAN). A LAN consists of multiple computers connected to each other.
There are many types of media that can connect computers together. The most common
media is CAT.5 cable (UTP or STP twisted pair wire.) On the other hand, wireless networks
do not use wires; instead they communicate over radio waves. Each computer must have a
Network Interface Card (NIC), which communicates the data between computers. A NIC is
usually a 10Mbps network card, or 10/100Mbps network card, or a wireless network card.
Most networks use hardware devices such as hubs or switches that each cable can be
connected to in order to continue the connection between computers. A hub
simply takes any data arriving through each port and forwards the data to all other ports. A
switch is more sophisticated, in that a switch can determine the destination port for a
specific piece of data. A switch minimizes network traffic overhead and speeds up the
communication over a network.
NAT (Network Address Translation)
For a computer to communicate with other computers on the Internet, it must have an IP
address. An IP (Internet Protocol) address is a unique 32-bit number that identifies the
location of your computer on a network. However, with the explosion of the Internet, the
number of available IP addresses is simply not enough.
This is where NAT comes to the rescue. Network Address Translation allows a single
device, such as a router, to act as an agent between the Internet (or “public network”) and a
local (or “private”) network. This means that only a single, unique IP address is required to
represent an entire group of computers.
Roaming
The ability to use a wireless device is able to move from one access point range to another
without losing the connection.
RTS/CTS Threshold Value
It should remain at its default setting of 2,347. A preamble is a signal used to synchronize
the transmission timing between two or more systems. A series of transmission pulses is
sent before the data to indicate that someone is about transmit data. This ensures that
systems receiving the information correctly when the data transmission starts.

Shared Key
It’s when both the sender and recipient share a secret key. Both units use this key for an
extended length of time, sometimes indefinitely. Any eavesdropper that discovers the key
may decipher all packets until the key is changed.
Signal Strength
The signal level indicates the strength of the signal as received at the wireless network
interface.
SSID (Service Set Identifier)
It’s the unique name shared among all points in a wireless network. The SSID must be
identical for all points in the network. It is case sensitive and must not exceed 32
characters.
TCP/IP
Transmission Control Protocol (TCP) with Internet Protocol (IP). The main internetworking
protocol used in the Internet.
UDP (User Datagram Protocol)
UDP provides a procedure for application programs to send messages to other programs
with a minimum of protocol mechanism. The protocol is transaction oriented, and delivery
and duplicate protection is not guaranteed. Applications requiring ordered reliable delivery
of streams of data should use the TCP.
What is Router?
A router is a device that forwards data packets from a source to a destination. Routers
forward data packets using IP addresses and not a MAC address. A router will forward data
from the Internet to a particular computer on your LAN. A router also determines the best
route that data packets should follow to ensure that the data packets are delivered properly.
WEP (Wired Equivalent Privacy)
A data privacy mechanism based on a 40 bit shared key algorithm, as described in the
IEEE 802 .11 standard. The optional cryptographic confidentiality algorithm specified by
IEEE 802.11 used to provide data confidentiality that is subjectively equivalent to the
confidentiality of a wired LAN medium that does not employ cryptographic techniques to
enhance privacy.
WPA (Wi-Fi Protected Access)
Wi-Fi Protected Access, a specification to improve the security level of wireless networks. It
uses 802.1x and EAP to control network access. Temporal Key Integrity Protocol (TKIP) is
