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) 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. 

¾

 

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. 

¾

 

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. 

¾

 

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. 

¾

 

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.
