Wireless-G Access Point
Multicasting
- Sending data to a group of nodes instead of a single destination.
Network
- A system that transmits any combination of voice, video and/or data
between users.
Node
- A network junction or connection point, typically a computer or work
station.
OFDM -
OFDM (Orthogonal Frequency Division Muliplexing) works by
breaking one high-speed data stream into a number of lower-speed data
streams, which are then transmitted in parallel. Each lower speed stream is used
to modulate a subcarrier.
Essentially, this creates a multi-carrier transmission
by dividing a wide frequency band or channel into a number of narrower fre-
quency bands or sub-channels.
Packet
- A unit of data routed between an origin and a destination in a network.
Passphrase
- Used much like a password, a passphrase simplifies the WEP
encryption process by automatically generating the WEP encryption keys for
Linksys products.
PC Card
- A credit-card sized removable module that contains memory, I/O,
or a hard disk.
Port
- A pathway into and out of the computer or a network device such as a
switch or router. For example, the serial and parallel ports on a personal com-
puter are external sockets for plugging in communications lines, modems and
printers.
RJ-45
(

ack-

) - A connector similar to a telephone connector that
holds up to eight wires, used for connecting Ethernet devices.
Roaming
- The ability to use a wireless device and be able to move from one
access point's range to another without losing the connection.
Router
- Protocol-dependent device that connects subnetworks together.
Routers are useful in breaking down a very large network into smaller subnet-
works; they introduce longer delays and typically have much lower throughput
rates than bridges.
RTS

to the receiving station requesting permission to transmit.

IEEE
(The

E
ngineers) - The IEEE
describes itself as "the world's largest technical professional society, promoting
the development and application of electrotechnology and allied sciences for
the benefit of humanity, the advancement of the profession, and the well-being
of our members."
The IEEE fosters the development of standards that often become national and
international standards. The organization publishes a number of journals, has
many local chapters, and several large societies in special areas, such as the
IEEE Computer Society.
Infrastructure
- An infrastructure network is a wireless network or other small
network in which the wireless network devices are made a part of the network
through the Access Point which connects them to the rest of the network.
IP Address
- In the most widely installed level of the Internet Protocol (IP)
today, an IP address is a 32-binary digit number that identifies each sender or
receiver of information that is sent in packet across the Internet. When you
request an HTML page or send e-mail, the Internet Protocol part of TCP/IP
includes your IP address in the message (actually, in each of the packets if more
than one is required) and sends it to the IP address that is obtained by looking
up the domain name in the Uniform Resource Locator you requested or in the
e-mail address you're sending a note to. At the other end, the recipient can see
the IP address of the Web page requestor or the e-mail sender and can respond
by sending another message using the IP address it received.
ISM band
- The FCC and their counterparts outside of the U.S. have set aside
bandwidth for unlicensed use in the ISM (Industrial, Scientific and Medical)
band. Spectrum in the vicinity of 2.4 GHz, in particular, is being made avail-
able worldwide. This presents a truly revolutionary opportunity to place con-
venient high-speed wireless capabilities in the hands of users around the globe.
LAN
- A local area network (LAN) is a group of computers and associated
devices that share a common communications line and typically share the
resources of a single processor or server within a small geographic area (for
example, within an office building).
MAC
(

Address
- A unique number assigned by the
manufacturer to any Ethernet networking device, such as a network adapter,
that allows the network to identify it at the hardware level.

through the Internet.

nternet
P
rotocol) - The basic com-
munication language or protocol of the Internet. It can also be used as a com-
munications protocol in a private network (either an intranet or an extranet).
When you are set up with direct access to the Internet, your computer is pro-
vided with a copy of the TCP/IP program just as every other computer that you
may send messages to or get information from also has a copy of TCP/IP.
Throughput
- The amount of data moved successfully from one place to anoth-
er in a given time period.
Topology
- A network's topology is a logical characterization of how the
devices on the network are connected and the distances between them. The
most common network devices include hubs, switches, routers, and gateways.
Most large networks contain several levels of interconnection, the most impor-
tant of which include edge connections, backbone connections, and wide-area
connections.
Upgrade
- To replace existing software or firmware with a newer version.
Upload
- To transmit a file over a network. In a communications session,
upload means transmit, download means receive.
UTP
- Unshielded twisted pair is the most common kind of copper telephone
wiring. Twisted pair is the ordinary copper wire that connects home and many
business computers to the telephone company. To reduce crosstalk or electro-
magnetic induction between pairs of wires, two insulated copper wires are
twisted around each other. Each signal on twisted pair requires both wires.
Since some telephone sets or desktop locations require multiple connections,
twisted pair is sometimes installed in two or more pairs, all within a single
cable.
WEP

bit, 128-bit, or 256-bit shared key algorithm, as described in the IEEE 802.11
standard.

Server
- Any computer whose function in a network is to provide user access
to files, printing, communications, and other services.
Software
- Instructions for the computer. A series of instructions that performs
a particular task is called a "program." The two major categories of software are
"system software" and "application software." System software is made up of
control programs such as the operating system and database management sys-
tem (DBMS). Application software is any program that processes data for the
user.
A common misconception is that software is data. It is not. Software tells the
hardware how to process the data.

Spread Spectrum
- Spread Spectrum technology is a wideband radio frequen-
cy technique developed by the military for use in reliable, secure, mission-crit-
ical communications systems. It is designed to trade off bandwidth efficiency
for reliability, integrity, and security. In other words, more bandwidth is con-
sumed than in the case of narrowband transmission, but the trade off produces
a signal that is, in effect, louder and thus easier to detect, provided that the
receiver knows the parameters of the spread-spectrum signal being broadcast.
If a receiver is not tuned to the right frequency, a spread-spectrum signal looks
like background noise. There are two main alternatives, Direct Sequence
Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS).
Static IP Address
- A permanent IP address that is assigned to a node in an IP
or a TCP/IP network.
Subnet Mask
- The method used for splitting IP networks into a series of sub-
groups, or subnets. The mask is a binary pattern that is matched up with the IP
address to turn part of the host ID address field into a field for subnets.
Switch
- 1. A data switch connects computing devices to host computers,
allowing a large number of devices to share a limited number of ports. 2. A
device for making, breaking, or changing the connections in an electrical cir-
cuit.
