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
Access Point. 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. (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).

MAC

Media Access Control. A protocol specified by the IEEE for determining
which devices have access to a network at any one time.

MAC Address

Media Access Control Address.

Also called the hardware or physical

address. A layer 2 address associated with a particular network device.
Most devices that connect to a LAN have a MAC address assigned to
them as they are used to identify other devices in a network. MAC
addresses are 6 bytes long.
