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.
DDNS (Dynamic Domain Name System): The capability of assigning a fixed host and domain
name to a dynamic Internet IP Address.
DHCP (Dynamic Host Configuration Protocol): A protocol that automatically configure the
TCP/IP parameters for the all the PC(s) that are connected to a DHCP server.
DMZ (Demilitarized Zone): A Demilitarized Zone allows one local host to be exposed to the
Internet for a special-purpose service such as Internet gaming or videoconferencing.
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.
DSL (Digital Subscriber Line): A technology allowing data to be sent or received over existing
traditional phone lines.
ISP (Internet Service Provider): A company that can provide access to the Internet.
MTU (Maximum Transmission Unit): The size in bytes of the largest packet that can be
transmitted.
NAT (Network Address Translation): NAT technology translates IP addresses of a local area
network to a different IP address for the Internet.
PPPoE (Point to Point Protocol over Ethernet): PPPoE is a protocol for connecting remote
hosts to the Internet over an always-on connection by simulating a dial-up connection.
SSID (Service Set Identification): It 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.
