106 GLOSSARY
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.
Infra-structure mode 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)
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.
ISP Internet Service Provider. An ISP is a business that provides connectivity to
the Internet for individuals and other businesses or organizations.
LAN 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).
