WLI-CF-S11G User’s Manual1166.1 Terms Related to the Network■ The following lists and describes the network-related terms in alphabetic order.ClientThe 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 inequipment including computers involved in the network. When the DHCP server exists on the network, the IP address canautomatically be assigned to the computers and AirStation on the network.When such equipment with the DHCP server function as the Windows 2000server or dial-up router exists on the network, the DHCP server functionmay be operating.Refer to the manual included in the Windows 2000 or dial-up router tocheck whether the DHCP server function is active on the Windows 2000server or dial-up router. Alternately, inquire to the manufacturer. When thenetwork includes only Windows Me/98/95 computers, no DHCP serverexists.ESS-ID (Extended Service Set ID)The ESS-ID is an identification code required to avoid interference duringcommunication between wireless LAN computers and the AirStation. Onlythe wireless LAN computers with the same ESS-ID as the AirStation cancommunicate with the AirStation. (The ESS-ID is not used incommunication between wireless LAN computers.) The initial setting of ESS-ID in the AirStation shows the "last six digits ofthe MAC address" plus "GROUP" (upper-case). The ESS-ID is case-sensitive and can consist of up to 32 alphanumeric characters and symbols.WLI-CF-S11G.book 116 ページ ２００２年３月１日　金曜日　午後６時１６分
6GlossaryWLI-CF-S11G User’s Manual 117FirmwareFirmware is software (programs) incorporated in such hardware as a router,modem, and terminal adapter (TA). Due to software integrated intohardware, it is assumed as being intermediate between hardware andsoftware.I/O port address (Input/Output port address)Input and output ports for receiving and sending information are providedbetween CPU and peripheral equipment. The I/O port address is a numberassigned to each equipment to distinguish which input/output ports are usedby which peripheral equipment.IRQ (Interrupt Request)The CPU in a computer carries out processing in accordance with a requestfrom peripheral equipment. However, it is impossible to predict when arequest is issued from which equipment. If the CPU constantly monitors allequipment to receive a request, the monitoring time will be longer than theprocessing time. Thus, when peripheral equipment wants the CPU toexecute a certain routine, a request interrupts the processing currentlyperformed by the CPU. The CPU then specifies the equipment which issuedthe request using the IRQ number, and starts the requested processing.Upon completion of the interrupt request processing, the CPU returns to theinterrupted processing.LAN (Local Area Network)LAN is a network established in a comparatively small area such as in onebuilding or on the premises of a campus. LAN generally uses transmissionspeeds 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 Manual118MAC address (Media Access Control address)The MAC address is a physical address specific to each piece of networkequipment. The MAC address consists of six bytes including the mostsignificant three bytes for the vendor code and the least significant threebytes for the user code. The vendor code is managed/assigned by the IEEEwhile the user code is controlled by the network equipment manufacturerusing its original number (without duplication). Namely, the MAC addressis a unique physical address. Based on this address, Ethernet sends andreceives packets (frames).Microsoft Network ClientMicrosoft Network Client is software installed on client computers to useWindows 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 theInternet.NetBEUI protocolNetBEUI protocol is a network transport protocol for exchanging data in asmall-scale or mid-scale LAN. NetBEUI is equivalent to the transport and network layer protocols of theOSI protocol model. These are integrated with NetBEUI to implement anefficient communication system in the workgroup LAN environment. Thisis supported in Windows Me/98/95/2000.Peer-to-peer connectionPeer-to-peer connection is communication carried out by computers in anequal 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.book 118 ページ ２００２年３月１日　金曜日　午後６時１６分
6GlossaryWLI-CF-S11G User’s Manual 119ProtocolProtocol is a procedure or a set of rules used to transmit data betweennetwork terminals. For example, when communicating between two computers, the conditionsrequired for communication can be established in a procedure to assurecorrectly ordered information transmission. Such requirements includewhich first starts sending what kind of message, what kind of messageshould respond to the received message, what format data should be in, whatshould be done in case of an error, and so on.Radio channelIf several types of wireless LAN are used with different ESS-IDs on thesame floor, the transfer speed of the local wireless network may be affectedwhen communication is performed on other wireless LANs. This is becauseradio signals with the same frequency are being used. To avoid thisproblem, a different frequency (radio channel) can be set for each type ofwireless LAN to communicate without mutual interference with otherwireless LANs. * When communicating between wireless LAN computers, the same radiochannel 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 thecomputer's peripheral equipment (mouse, keyboard, etc.), PCI bus adapter,wireless LAN card, and such.WLI-CF-S11G.book 119 ページ ２００２年３月１日　金曜日　午後６時１６分
WLI-CF-S11G User’s Manual120TCP/IP (Transmission Control Protocol/Internet Protocol)TCP/IP is equivalent to the network layer and transport layer of the OSIreference 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 alsoincluded.• TCP/IP is the Internet standard protocolUSB (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, noconflict with other devices due to no IRQ. The USB is supported inWindows Me/98/2000.WECA (Wireless Ethernet Compatibility Alliance)WECA is an organization which promotes the IEEE 802.11b High-Ratestandard for propagation of the unified wireless LAN and ensures the mutualoperation of compliant products. It was established in 1999 by sixcompanies of Lucent Technologies, Intersil, Nokia, 3com, SymbolTechnologies, and Aironet Wireless Communications that played a leadingrole in development of the IEEE 802.11 standard. The organization has been developing activities for wireless LANpropagation on world-wide basis. We have currently participated in theorganization.
