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.
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.
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 - 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.
