130 CHAPTER : GLOSSARY

Router	A device that acts as a central hub by connecting to each computer's
	network interface card and managing the data traffic between the local
	network and the Internet.
Half Duplex	A system that allows packets to transmitted and received, but not at the
	same time. Contrast with full duplex.
Hub	A device that regenerates LAN traffic so that the transmission distance of
	that signal can be extended. Hubs are similar to repeaters, in that they
	connect LANs of the same type; however they connect more LANs than a
	repeater and are generally more sophisticated.
IEEE	Institute of Electrical and Electronics Engineers. This American
	organization was founded in 1963 and sets standards for computers and
	communications.
IETF	Internet Engineering Task Force. An organization responsible for
	providing engineering solutions for TCP/IP networks. In the network
	management area, this group is responsible for the development of the
	SNMP protocol.
Infrastructure mode	Infrastructure mode is the wireless configuration supported by the Router.
	You will need to ensure all of your clients are set up to use infrastructure
	mode in order for them to communicate with the Access Point built into
	your Router. (see also Ad Hoc mode)
IP	Internet Protocol. IP is a layer 3 network protocol that is the standard
	for sending data through a network. IP is part of the TCP/IP set of
	protocols that describe the routing of packets to addressed devices. An IP
	address consists of 32 bits divided into two or three fields: a network
	number and a host number or a network number, a subnet number, and
	a host number.
IP Address	Internet Protocol Address. A unique identifier for a device attached to
	a network using TCP/IP. The address is written as four octets separated
	with periods (full-stops), and is made up of a network section, an
	optional subnet section and a host section.
