Appendix C: Glossary

802.11b: The 802.11b standard specifies a wireless networking at 11 Mbps using

direct-sequence spread-spectrum (DSSS) technology and operating in the unlicensed radio

spectrum at 2.4GHz, and WEP encryption for security. 802.11b networks are also referred to as

Wi-Fi networks.

802.11g: Specification for wireless networking at 54 Mbps using direct-sequence

spread-spectrum (DSSS) technology, using OFDM modulation and operating in the unlicensed

radio spectrum at 2.4GHz, and backward compatibility with IEEE 802.11b devices, and WEP

encryption for security.

Access Point (AP): A wireless LAN transceiver or base station that can connect a wired LAN to

one or many wireless devices. Access points can also bridge to each other.

DNS (Domain Name System): An Internet Service that translates the names of websites into IP

addresses.

Domain Name: A descriptive name for an address or group of addresses on the Internet.

DoS (Denial of Service): A hacker attack designed to prevent your computer or network from

operating or communicating.

DSL (Digital Subscriber Line): A technology that allows data to be sent or received over

existing traditional phone lines.

ISP (Internet Service Provider): A company that provides access to the Internet.

MTU (Maximum Transmission Unit):The size in bytes of the largest packet that can be

transmitted.

SSID: A Service Set Identification is a thirty-two character (maximum) alphanumeric key

identifying a wireless local area network. For the wireless devices in a network to communicate

with each other, all devices must be configured with the same SSID. This is typically the

configuration parameter for a wireless PC card. It corresponds to the ESSID in the wireless Access

Point and to the wireless network name.

WEP (Wired Equivalent Privacy): A data privacy mechanism based on a 64-bit or 128-bit or

152-bit shared key algorithm, as described in the IEEE 802.11 standard.

Wi-Fi: A trade name for the 802.11b wireless networking standard, given by the Wireless

Ethernet Compatibility Alliance (WECA, see http://www.wi-fi.net), an industry standards group

promoting interoperability among 802.11b devices.

WLAN (Wireless Local Area Network): A group of computers and associated devices

communicate with each other wirelessly, which network serving users are limited in a local area.
