  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

  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.
