GLOSSARY
Access Point
An access point serves as a bridge between an existing wired network and wireless
devices. The AirStation Pro is a type of access point.
CD-ROM (Compact Disc Read-Only Memory)
An optical disc that is physically the same as an audio CD, but contains computer
data. Storage capacity is approximately 680 megabytes. CD-ROM’s are
interchangeable between different types of computers.
Configuration PC
This is a PC that is used to configure the settings on the AirStation Pro. It is
recommended that you use a Wired LAN PC to configure the AirStation Pro.
Crossover cable
This cable can be used to cascade hubs, or to connect two Ethernet stations backto-back without a hub. It works with both 10Base-T and 100Base-TX.
DHCP (Dynamic Host Configuration Protocol) server
This is a function that adjusts bandwidth automatically depending on the
communication traffic. IP addresses can be automatically assigned to the network
PC’s and the AirStation Pro if a DHCP server exists on the network. This function
is also available if there are any devices on the network with their own built-in
DHCP server function, such as a Windows 2000/NT server or a dial-up router.
For further information on enabling this function, please refer to the manuals for
these devices, or consult their manufacturers.
There is no DHCP server on a network that contains only Windows 95/98/ME PCs.
DNS (Domain Name Server (or Service))
Software that enables users to locate computers on the Internet by host name. A
DNS server is a database of host names and IP addresses. DNS returns the IP
addresses when presented with a host name.
Glossary
Page 90
ESS-ID (Extended Service Set ID)
An ID used to regulate communication between wireless LAN PC’s and an
AirStation Pro.This ID allows you to access the network and connect to an access
point.
The ESS-ID forms part of the AirStation Pro address and part of the PC/laptop
address, acting as a special identifier. In order to be able to communicate with
an AirStation Pro, a Wireless LAN PC must be configured with the same ESS-ID.
This value is not used for communications between Wireless LAN PC’s.
There is a different ESS-ID for each access point. The factory/default setting of
the ESS-ID is the last six digits of the MAC address followed by the word
“GROUP”.
The ESS-ID can consist of up to 32 alphanumeric characters and symbols, and is
case-sensitive.
Ethernet
The most popular type of LAN, which send its communications through radio
frequency signals carried by a coaxial cable. Each computer checks to see if
another computer is transmitting and waits its turn to transmit. If two computers
accidentally transmit at the same time and their messages collide, they wait and
send again in turn.
Firmware
Firmware is the name given to the software (programs) that is written onto readonly memory (ROM) such as routers, modems, and terminal adapters. It is a
combination of software and hardware.
IEEE (Institute of Electrical and Electronic Engineers)
A world-wide professional association for electrical and electronic engineers,
which sets standards for telecommunications and computing applications.
IP (Internet Protocol) address
A numeric address such as 123.231.32.2 that the domain server translates into a
domain name. The IP address is an identifier for a computer or a device on a
TCP/IP network.
Page 91
The protocol within TCP/IP that governs the break-up of data messages into
packets from sender to destination network and sender to distribution network
and station, and the re-assembly of the packets into original data messages at
the destination.
LAN (Local Area Network)
A LAN is a network that connects computers in a relatively small area, such as a
single building or campus. In other words, it is a network that serves users within
a confined geographical area. The typical LAN band rate varies between 10 Mbps
and 100 Mbps.
LED (Light Emitting Diode)
A type of semi-conductor diode that emits visible or infrared light when current
passes through it. Visible LED’s are used as indicator lights; for example, the
light that shows a computer, hardware device or printer is turned on. Infrared
LED’s are used in remote-control devices.
MAC Address (Media Access Control Address)
This is a physical address specific to each network device.
The MAC address consists of six bytes. The first three bytes constitute the vendor
code, and the last three bytes make up the user code.
The vendor code is managed and assigned by IEEE.
The network device manufacturer assigns a unique user code for each user,
therefore, each MAC address is assigned as a physical address unique throughout
the world. In Ethernet, frames are transmitted and received using the MAC
addresses.
Protocol
Protocols are the procedures and regulations designed so that computers can
send and exchange information with a minimum of errors. For example, they can
ensure efficient data transmission between two companies by establishing
procedures for all communication conditions between them.
Roaming Function (Bridging LAN’s)
The AirStation Pro can connect multiple PC’s as a repeater bridge between rooms
and buildings. The roaming function allows anyone in the office or on-the-go to
Page 92
stay connected without being tied down to wired installations. The roaming
function automatically changes access points.
Straight-through cable
Bulk cable and connectors used to ensure data transmission.
TCP/IP (Transmission Control Protocol Internet Protocol)
TCP/IP is basically a communications protocol. The Transmission Protocol (TCP)
functions on top of the Internet Protocol (IP). These protocols were developed
to enable communication between different types of computers and computer
networks.
TCP/IP generally includes application protocols such as Telnet and FTP.
TCP/IP is the standard Internet protocol.
WDS (Wireless Distribution System)
WDS is applied to the communication between up to six access points.
Web browser
A software application used to navigate the Internet. It provides a graphical user
interface (or GUI) so that the user can click menus, icons, or buttons rather than
learning difficult computer commands.
WEP (Wired Equivalent Privacy)
By setting an encryption key in the AirStation Pro, you can prevent external
decryption of packets. Whenever you open communications with an AirStation
Pro that has been configured with an encryption key, you must enter the same
encryption key in the Client Manager.
Wired LAN and Wireless LAN
Wired LAN: LAN connected by cables.
Wireless LAN: LAN that uses wireless (radio) communication.
Page 93
Wireless channel
When connecting between Wireless LAN computers, the same Wireless
channel must be used in all the Wireless LAN computers involved. If you
change the Wireless channel, it may cause radio interference with other
Wireless devices.
