Wireless LAN
When installing Wireless LAN cards, the channel configuration is 
managed as follows: 
■ For wireless clients that operate in a Wireless LAN Infrastructure, the 
Wireless LAN card will automatically start operation at the channel 
identified by the Wireless LAN Access Point. When roaming between 
different access points the station can dynamically switch to another 
channel if required. 
■ For Wireless LAN cards installed in wireless clients operating in a 
peer-to-peer mode, the card will use the default channel 10. 
■ In a Wireless LAN Access Point, the Wireless LAN card will use the 
factoryset default channel (printed in bold), unless the LAN 
Administrator selected a different channel when configuring the 
Wireless LAN Access Point device.

Glossary
binary: The base two number system composed of zeros and ones (off or 
on), used by most digital computers. The right most digit of a 
binary number has a value of 1, the next a value of 2, then 4, 8, 16, 
and so on. For example, the binary number 101 has a value of 5. 
See also ASCII. 
BIOS: Basic Input Output System. The firmware that controls data flow 
within the computer. See also firmware. 
bit: Derived from “binary digit,” the basic unit of information used by the 
computer. It is either zero or one. Eight bits is one byte. See also 
byte. 
Bluetooth: A short-range radio technology designed to simplify wireless 
communication among computers, communication devices and 
the Internet. 
board: A circuit board. An internal card containing electronic 
components, called chips, which perform a specific function or 
increase the capabilities of the system. 
boot: Short for bootstrap. A program that starts or restarts the computer. 
The program reads instructions from a storage device into the 
computer’s memory. 
bps: Bits per second. Typically used to describe the data transmission 
speed of a modem. 
buffer: The portion of the computer’s memory where data is temporarily 
stored. Buffers often compensate for differences in the rate of flow 
from one device to another. 
bus: An interface for transmission of signals, data or electric power. 
byte: The representation of a single character. A sequence of eight bits 
treated as a single unit; also the smallest addressable unit within 
the system. 
C

processor speed and data transfer rate. When the CPU reads data 
from main memory, it stores a copy of this data in cache memory. 
The next time the CPU needs that same data, it looks for it in the 
cache memory rather than the main memory, which saves time. 
The computer has two cache levels. Level one is incorporated into 
the processor and level two resides in external memory. 
card: Synonym for board. See board. 
CardBus: An industry standard bus for 32-bit PC Cards. 
capacity: The amount of data that can be stored on a magnetic storage 
device such as a diskette (floppy disk) or hard disk. It is usually 
described in terms of kilobytes (KB), where one KB = 1024 bytes 
and megabytes (MB), where one MB = 1024 KB. 
CD-ROM: A Compact Disk-Read Only Memory is a high capacity disk 
that can be read from but not written to. The CD-ROM drive uses a 
laser, rather than magnetic heads, to read data from the disk.
