LOSSARY

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.

Institute of Electrical and Electronics Engineers. This American 
organization was founded in 1963 and sets standards for computers and 
communications.

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.

Infra-Structure mode is the 802.11b configuration supported by the 
Gateway. You will need to ensure all of your clients are set up to use 
infra-structure mode in order for them to communicate with the Access 
Point built into your Gateway. (see also Ad Hoc mode)

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.

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.

Internet Service Provider. An ISP is a business that provides connectivity to 
the Internet for individuals and other businesses or organizations.

Local Area Network. A network of end stations (such as PCs, printers, 
servers) and network devices (hubs and switches) that cover a relatively 
small geographic area (usually not larger than a floor or building). LANs 
are characterized by high transmission speeds over short distances (up to 
1000 metres).
