6.1 Terms Related to the Network
■ The following lists and describes the network-related
terms in alphabetic order.
Client
The party which receives services in the client-server system is called
"client" while the party which provides services is called "server."
Information and services in the server can be used from a client computer.
DHCP server (Dynamic Host Configuration Protocol server)
When configuring a network using TCP/IP, the IP address must be set in
equipment including computers involved in the network.
When the DHCP server exists on the network, the IP address can
automatically be assigned to the computers and AirStation on the network.
When such equipment with the DHCP server function as the Windows 2000
server or dial-up router exists on the network, the DHCP server function
may be operating.
Refer to the manual included in the Windows 2000 or dial-up router to
check whether the DHCP server function is active on the Windows 2000
server or dial-up router. Alternately, inquire to the manufacturer. When the
network includes only Windows Me/98/95 computers, no DHCP server
exists.
ESS-ID (Extended Service Set ID)
The ESS-ID is an identification code required to avoid interference during
communication between wireless LAN computers and the AirStation. Only
the wireless LAN computers with the same ESS-ID as the AirStation can
communicate with the AirStation. (The ESS-ID is not used in
communication between wireless LAN computers.)
The initial setting of ESS-ID in the AirStation shows the "last six digits of
the MAC address" plus "GROUP" (upper-case). The ESS-ID is case-
sensitive and can consist of up to 32 alphanumeric characters and symbols.

Firmware
Firmware is software (programs) incorporated in such hardware as a router,
modem, and terminal adapter (TA). Due to software integrated into
hardware, it is assumed as being intermediate between hardware and
software.
I/O port address (Input/Output port address)
Input and output ports for receiving and sending information are provided
between CPU and peripheral equipment. The I/O port address is a number
assigned to each equipment to distinguish which input/output ports are used
by which peripheral equipment.
IRQ (Interrupt Request)
The CPU in a computer carries out processing in accordance with a request
from peripheral equipment. However, it is impossible to predict when a
request is issued from which equipment. If the CPU constantly monitors all
equipment to receive a request, the monitoring time will be longer than the
processing time. Thus, when peripheral equipment wants the CPU to
execute a certain routine, a request interrupts the processing currently
performed by the CPU. The CPU then specifies the equipment which issued
the request using the IRQ number, and starts the requested processing.
Upon completion of the interrupt request processing, the CPU returns to the
interrupted processing.
LAN (Local Area Network)
LAN is a network established in a comparatively small area such as in one
building or on the premises of a campus. LAN generally uses transmission
speeds of 10 Mbps to 100 Mbps.
WLI-CF-S11G.book 117 ページ ２００２年３月１日 金曜日 午後６時１６分
WLI-CF-S11G User’s Manual118
MAC address (Media Access Control address)
The MAC address is a physical address specific to each piece of network
equipment. The MAC address consists of six bytes including the most
significant three bytes for the vendor code and the least significant three
bytes for the user code. The vendor code is managed/assigned by the IEEE
while the user code is controlled by the network equipment manufacturer
using its original number (without duplication). Namely, the MAC address
is a unique physical address. Based on this address, Ethernet sends and
receives packets (frames).
Microsoft Network Client
Microsoft Network Client is software installed on client computers to use
Windows Me/98/2000 server services in a LAN. It usually uses "NetBEUI"
or "TCP/IP" for the protocol. The TCP/IP protocol is used to connect to the
Internet.
NetBEUI protocol
NetBEUI protocol is a network transport protocol for exchanging data in a
small-scale or mid-scale LAN.
NetBEUI is equivalent to the transport and network layer protocols of the
OSI protocol model. These are integrated with NetBEUI to implement an
efficient communication system in the workgroup LAN environment. This
is supported in Windows Me/98/95/2000.
Peer-to-peer connection
Peer-to-peer connection is communication carried out by computers in an
equal relationship with each other via LAN or WAN.
Unlike a server-client system, the settings can be made to use resources
(drives and folders) in other computers from any computer on the network.

WLI-CF-S11G User’s Manual 119
Protocol
Protocol is a procedure or a set of rules used to transmit data between
network terminals.
For example, when communicating between two computers, the conditions
required for communication can be established in a procedure to assure
correctly ordered information transmission. Such requirements include
which first starts sending what kind of message, what kind of message
should respond to the received message, what format data should be in, what
should be done in case of an error, and so on.
Radio channel
If several types of wireless LAN are used with different ESS-IDs on the
same floor, the transfer speed of the local wireless network may be affected
when communication is performed on other wireless LANs. This is because
radio signals with the same frequency are being used. To avoid this
problem, a different frequency (radio channel) can be set for each type of
wireless LAN to communicate without mutual interference with other
wireless LANs.
* When communicating between wireless LAN computers, the same radio
channel must be used in all the wireless LAN computers involved.
Resource (system resource)
Resource is a generic name for IRQ and I/O port addresses assigned to the
computer's peripheral equipment (mouse, keyboard, etc.), PCI bus adapter,
wireless LAN card, and such.

TCP/IP (Transmission Control Protocol/Internet Protocol)
TCP/IP is equivalent to the network layer and transport layer of the OSI
reference model, and is defined by the RFC. Therefore, execution of TCP/
IP enables different terminals to communicate each other.
• Normally, application protocols such as TELNET and FTP are also
included.
• TCP/IP is the Internet standard protocol
USB (Universal Serial Bus)
USB is a new standard for connecting computers and peripheral equipment.
Its features include data transfer capability at a maximum speed of 12 Mbps,
compatibility with the Hot Swap feature allowing insertion and removal to/
from the USB port with the computer or peripheral equipment turned on, no
conflict with other devices due to no IRQ. The USB is supported in
Windows Me/98/2000.
WECA (Wireless Ethernet Compatibility Alliance)
WECA is an organization which promotes the IEEE 802.11b High-Rate
standard for propagation of the unified wireless LAN and ensures the mutual
operation of compliant products. It was established in 1999 by six
companies of Lucent Technologies, Intersil, Nokia, 3com, Symbol
Technologies, and Aironet Wireless Communications that played a leading
role in development of the IEEE 802.11 standard.
The organization has been developing activities for wireless LAN
propagation on world-wide basis. We have currently participated in the
organization. The latest information about the participating companies and
Wi-Fi certified products can be obtained from the web site below.
