Appendix B: Glossary

802.11b	One of the IEEE standards for wireless networking hardware.
	Products that adhere to a specific IEEE standard will work
	with each other, even if they are manufactured by different
	companies. The 802.11b standard specifies a maximum data
	transfer rate of 11Mbps, an operating frequency of 2.4GHz,
	and WEP encryption for security. 802.11b networks are also
	referred to as Wi-Fi networks.
802.11g	Refers to the proposed of the IEEE 802.11 standard for
	wireless networking. The 802.11g specifications used by
	NetComm specifies a maximum data transfer rate of 54Mbps
	using OFDM modulation, an operating frequency of
	2.4GHz, backward compatibility with IEEE 802.11b devices
	and WEP encryption for security.
Ad-hoc Network	An ad-hoc network is a group of computers, each with a
	wireless adapter, connected as an independent 802.11
	wireless LAN. Ad-hoc wireless computers operate on a
	peer-to-peer basis, communicating directly with each other
	without the use of an access point. Ad-hoc mode is also
	referred to as an Independent Basic Service Set (IBSS) or as
	peer-to-peer mode, and is useful at a departmental scale or
	SOHO operation.
CTS (Clear To Send)	An RS-232 signal sent from the receiving station to the
	transmitting station that indicates it is ready to accept data.
Default Gateway	The router used to forward all traffic that is not addressed to
	a station within the local subnet.
DHCP	(Dynamic Host Configuration Protocol) - A protocol that
	lets network administrators manage centrally and automate
	the assignment of Internet Protocol (IP) addresses in an
	organization's network. Using the Internet's set of protocol
	(TCP/IP), each machine that can connect to the Internet
	needs a unique IP address. When an organization sets up its
	computer users with a connection to the Internet, an IP
	address must be assigned to each machine. Without DHCP,
	the IP address must be entered manually at each computer
	and, if computers move to another location in another part of
	the network, a new IP address must be entered. DHCP lets a
	network administrator supervise and distribute IP addresses
	from a central point and automatically sends a new IP
	address when a computer is plugged into a different place in
	the network. DHCP uses the concept of a "lease" or amount
	of time that a given IP address will be valid for a computer.
