	The lease time can vary depending on how long a user is
	likely to require the Internet connection at a particular
	location. It's especially useful in education and other
	environments where users change frequently. Using very
	short leases, DHCP can dynamically reconfigure networks in
	which there are more computers than there are available IP
	addresses.
	DHCP supports static addresses for computers containing
	Web servers that need a permanent IP address. DNS - The
	domain name system (DNS) is the way that Internet domain
	name are located and translated into Internet Protocol (IP)
	addresses. A domain name is a meaningful and easy-to-
	remember "handle" for an Internet address.
D S S S	(Direct-Sequence Spread Spectrum) - DSSS generates a
	redundant bit pattern for all transmitted data. This bit
	pattern is called a chip (or chipping code). Even if one or
	more bits in the chip are damaged during transmission,
	statistical techniques embedded in the receiver can recover
	the original data without the need for retransmission. To an
	unintended receiver, DSSS appears as low power wideband
	noise and is rejected (ignored) by most narrowband receivers.
	However, to an intended receiver (i.e. another wireless LAN
	endpoint), the DSSS signal is recognized as the only valid
	signal, and interference is inherently rejected (ignored).
Dynamic IP Address	An IP address that is automatically assigned to a client
	station in a TCP/IP network, typically by a DHCP server.
	Network devices that serve multiple users, such as servers
	and printers, are usually assigned static IP addresses.
ESS	(Extended Service Set) - A set of more than two or more
	BSSs (multiple access points) forming a single network.
Firmware	Code that is written onto read-only memory (ROM) or
	programmable read-only memory (PROM). Once firmware
	has been written onto the ROM or PROM, it is retained
	even when the device is turned off.
IEEE	The Institute of Electrical and Electronics Engineers. The
	IEEE describes itself as "the world's largest technical
	professional society-promoting the development and
	application of electrotechnology and allied sciences for the
	benefit of humanity, the advancement of the profession, and
	the wellbeing of our members." The IEEE fosters the
	development of standards that often become national and
	international standards. The organization publishes a number
	of journals, has many local chapters, and several large
