• 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 PCs 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.
