Glossary   57
Glossary
Ad-hoc mode
A small peer-to-peer network mode, in which wireless clients are connected to 
each other directly without using an access  point. Some of the wireless clients 
are part of the network for a limited dura tion. They are also in close proximity 
with the rest of the network. Accordi ng to the IEEE 802.11b specification, 
Ad-hoc mode is referred to as  an independent basic service set.
Antenna
A device that intercepts radio frequency  (RF) waves from the atmosphere and 
converts them to corresponding signal voltages.
Access Point (AP)
A networking device that transparently bridges wireless computers to a w\
ired 
local network.
Bandwidth
A measure of the maximum rate of data transfer. A higher bandwidth allows 
more data transmission in a given peri od of time. For digital services, the 
bandwidth is usually expressed  in bits or bytes per second.
BSS (Basic Service Set)
A group of wireless clients and an  access point using the same ID (SSID). 
						

							
Glossary   58 
DHCP (Dynamic Host Configuration Protocol)
A method of assigning a temporary IP address to a host, such as a computer, 
connected on a specific network. With  dynamic addressing, a particular host 
may have a different IP address each  time it connects to the network.
Dynamic IP address
See DHCP (Dynamic Host Configuration Protocol) .
Encryption
A procedure to convert a file from its original form to one that can be read 
only by the intended recipient.
IEEE 802.11
A family of wireless network standards, which includes 802.11a, 802.11b, 
802.11e, and 802.11g. The original 80 2.11 standard was first approved in 
1997 but was not very successful because  it was relatively slow at 2 Mbps.
IEEE 802.11b
A high-bit wireless network standard that works on the 2.4 GHz band and 
utilizes DSSS (direct sequence spread spect rum) technology. It offers data bit 
rates of up to 11 Mbps and the range  is from 200 to 300 feet for maximum 
speed. 
						

							
Glossary   59
IEEE 802.11g
A new 802.11 standard for wireless networking hardware. The 802.11g 
standard specifies a maximum data transfer rate of 54 Mbps, an operating 
frequency of 2.4 GHz, backward comp atibility with 802.11b devices and 
WEP encryption for security.
Infrastructure mode
A LAN or other small network mode in wh ich wireless clients are part of the 
network and use one or more access point s to connect to a wired network. 
Each access point is connected to the  Ethernet network using a standard 
Ethernet cable. In IEEE 802.11b speci fication, the infrastructure mode is 
referred to as the Basic Service Set.
IP (Internet Protocol)
The standard protocol within TCP/IP that  defines the basic unit of information 
by breaking down data messages into  packets, routing and transporting the 
packets over networks, then reassembling  the packets at their destination. IP 
corresponds to the Network layer  (layer 3) in the ISP/OSI model.
IP address
The address for a computer on a TCP/IP  network. The IP address identifies a 
particular machine on a network. The  format of an IP address is a 32-bit 
numeric address written as four number s separated by periods. Each number 
can be 0 to 255, for example, 11.160.1 0.240 is an IP address. Any machine 
connected to the Internet is  assigned an IP address. 
						

							
Glossary   60 
LAN (Local Area Network)
A computer network that spans a relatively small area. Most LANs are 
confined to an office, single  building, or group of buildings.
MAC (Media Access Control) address
A unique number that is assigned by  manufacturers to each Ethernet network 
device. A MAC address lets a network id entify Ethernet network devices at 
the hardware level.
Router
A hardware device that connects two sepa rately functional networks using the 
same or different protocols. Routers l ook at the destination addresses on the 
packets passing through them and then  decide which route to send them on.
SSID (Service Set Identity)
A group name shared by all members of  an IEEE 802.11 standard wireless 
network. Only wireless devices with  the same SSID are allowed to establish 
connections.
Static IP address
A permanent IP address assigned to a co mputer (host) connected on a specific 
network.
TCP/IP (Transmission Control Protocol/Internet Protocol)
A suite of communication protocols that  are used by computers or networking 
devices on the Internet so that they can communicate with each other. TCP/IP 
uses several protocols, the two main being TCP and IP. 
						

							
Glossary   61
USB (Universal Serial Bus)
A plug-and-play interface that allows the user to attach a device without 
having to add an adapter card and turning off the computer.
WEP (Wired Equivalent Privacy)
A wired security policy defined by  the IEEE 802.11 working group. WEP 
uses the RC-4 40-bit encryption algorithm  to scramble all data before it is 
transmitted. Vendors add proprietary encryption features to their software, 
taking the encryption level up to 128 bits.
Wi-Fi
Wi-Fi is promoted by the Wireless Ethe rnet Compatibility Alliance (WECA). 
It places a stamp of certification on wi reless products that are interoperable 
with other 802.11b compliant products.
