Access point - (Also called AP.) A wireless network transceiver or "base station" hub, often used to connect a local area network to one or more wireless devices. An access point can also provide a communication link to a wired local area network.

Ad Hoc - A client setting for a wireless local area network that allows devices connected to the network to communicate with one another directly, independent of an access point or router.

Bridge - A product that connects a local area network to another local area network that uses the same protocol (for example, wireless, Ethernet or token ring). Wireless bridges are commonly used to link buildings in campuses.

Client - An application on a computer or device connected to a network that requests services (files, print capability) from another connected computer or device on the network.

Device-to-device - See Ad Hoc.

DHCP - Dynamic Host Configuration Protocol: a utility that enables a server to dynamically assign IP addresses from a predefined list and limit their time of use so they can be reassigned. Without DHCP, all of the IP addresses of all the clients on the network would have to be manually entered. With DHCP, whenever a client connects to the network, it automatically gets an IP address assigned to it.

DNS - Domain Name System (or Service, or Server): a program that translates domain names to IP addresses by accessing a database maintained on a collection of Internet servers. The program works behind the scenes to facilitate surfing the Web with alpha versus numeric addresses. A DNS server converts a name like mywebsite.com to a series of numbers like 107.22.55.26. Every Web site has its own specific IP address on the Internet.

Domain name - The portion of a URL or Web address that identifies a specific Web site. For example, the domain name portion of the URL http://www.kodak.com is kodak.com. All domain names have a suffix that indicates the top level domain (TLD) it belongs to. Examples include:

com: US commercial business

gov: US government agency

edu: US educational institution

mil: US military organization

net: US network organization

org: US nonprofit organization

au: Australia

br: Brazil

ca: Canada

de: Germany

do: Dominican Republic

es: Spain

fr: France

it: Italy

nl: Netherlands

pr: Puerto Rico

pt: Portugal

ru: Russian Federation

uk: United Kingdom

DSL - Digital Subscriber Lines: various technology protocols for high-speed data, voice and video transmission over ordinary twisted-pair copper POTS (Plain Old Telephone Service) telephone wires.

Dynamic IP address - An IP address assigned to a client, each time the client connects to the network. The dynamic IP address is configured by the DHCP server and can be different each time the client connects to the network.

Encryption key - An alphanumeric (letters and/or numbers) series that enables data to be encrypted then decrypted so it can be safely shared among members of a network. WEP uses an encryption key that automatically encrypts outgoing wireless data. On the receiving side, the same encryption key enables the computer to automatically decrypt the information so it can be read.

Infrastructure - A client setting for a local area network that allows devices connected to the network to communicate with one another through a central access point or router. This configuration is commonly used in wireless home networks.

IP - Internet Protocol: technology that supports voice, data and video transmission via IP-based local area networks, wide area networks, and the Internet. This includes VoIP (Voice over IP).

IP address - A number that identifies each sender or receiver of information that is sent across the Internet.

Network name - Identifies the wireless network for all the shared components. During the installation process for most wireless networks, you must enter the network name or SSID. Different network names are used when setting up your individual computer, wired local area network, or workgroup.

Passphrase - A text string used for WPA security on a Wi-Fi wireless network. A passphrase may contain up to 31 alphanumeric characters, including spaces and other special characters.

Router - An access point (AP) or hub that sends data from one local area network (LAN) or wide area network (WAN) to another. A router monitors and controls data flow and sends information using the most efficient route based on traffic load, line costs, speed, bad connections, etc.

SSID - Service Set Identifier: also referred to as a network name, since it is essentially a name that identifies a wireless network. The identifier is attached to the wireless local area network (WLAN) and acts as an identifier when a device tries to connect to the system. A device will not be permitted to join the network unless it can provide the unique SSID. An SSID can be broadcast by the network router, allowing devices to detect it as an available network. An SSID does not supply security to the network.

SSL - Secure Sockets Layer: a commonly used encryption scheme used by many online retail and banking sites to protect the financial integrity of transactions.

TCP/IP - Transmission Control Protocol/Internet Protocol: the underlying technology behind the Internet and communications between computers in a network.

URL - Uniform Resource Locator: also referred to as a Web address, since it identifies the location of a file or resource on the Web. For example, the URL for the Eastman Kodak Company Web site is http://www.kodak.com.

WEP - Wired Equivalent Privacy: basic wireless security provided by Wi-Fi. In some instances, WEP may be all a home or small-business user needs to protect wireless data. WEP is available in 40-bit (also called 64-bit), or in 108-bit (also called 128-bit) encryption modes. As 108-bit encryption provides a longer algorithm that takes longer to decode, it can provide better security than basic 40-bit (64-bit) encryption.

WEP key - A text string used for WEP security on a Wi-Fi wireless network. A WEP key with 10 or 23 characters can include numbers and the letters A - F and are not case-sensitive. 5 and 13 character WEP keys can include numbers and all letters (as well as some special characters) and are case sensitive.

WPA - Wi-Fi Protected Access: a Wi-Fi security standard that provides a high level of wireless network security. It uses data encryption through the Temporal Key Integrity Protocol (TKIP). TKIP scrambles the keys and ensures that the keys haven't been tampered with. User authentication is performed through the Extensible Authentication Protocol (EAP) to ensure that only authorized network users can access the network.

Wi-Fi - Wireless Fidelity: a term developed by the Wi-Fi Alliance commonly used to describe any type of 802.11 standard wireless network. Products tested and approved as "Wi-Fi Certified" (a registered trademark) by the Wi-Fi Alliance are certified as interoperable with each other, even if they are from different manufacturers.
