802.11n - 802.11n builds upon previous 802.11 standards by adding MIMO 
(multiple-input multiple-output). MIMO uses multiple transmitter and receiver antennas to 
allow for increased data throughput via spatial multiplexing and increased range by 
exploiting the spatial diversity, perhaps through coding schemes like Alamouti coding. 
The Enhanced Wireless Consortium (EWC) [3] was formed to help accelerate the IEEE 
802.11n development process and promote a technology specification for 
interoperability of next-generation wireless local area networking (WLAN) products.

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.   
¾
 
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. 
¾
 
DNS (Domain Name System) - An Internet Service that translates the names of websites 
into IP addresses. 
¾
 
Domain Name - A descriptive name for an address or group of addresses on the 
Internet.  
¾
 
DSL (Digital Subscriber Line) - A technology that allows data to be sent or received over 
existing traditional phone lines. 
¾
 
ISP (Internet Service Provider) - A company that provides access to the Internet. 
¾
 
MTU (Maximum Transmission Unit- The size in bytes of the largest packet that can 
be transmitted. 
¾
 
NAT (Network Address Translation) - NAT technology translates IP addresses of a local 
area network to a different IP address for the Internet. 
¾
 
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
