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 securit y. 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 securit y.
• DDNS (Dynamic Domain Name System): The capability of assigning a fixed host and
domain name to a dynamic Internet IP Address.
• DHCP (Dynamic Host Confi guration 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 Identifi cation): It is a thirty-t wo 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 net working standard, given by the Wireless
