IANA Internet Assigned Numbers Authority. A regulatory group that maintains all assigned
and registered Internet numbers, such as IP and multicast addresses.
ICMP Internet Control Message Protocol is a protocol designed to allow hosts to send error
and control messages to other network devices. Basically ICMP provides
communication between the Internet Protocol (IP) software on network devices. The
short ICMP messages use IP packets and are usually processed by the IP software,
rather than presented to the user at the application level.
IEC The International Electro-Technical Commission. an international organization that
writes standards for safety for electrical and other equipment. Many IEC standards
were adopted from the German VDE, which was the main historical
standards-writing body in Europe. One goal of the IEC is to harmonize differing
standards between European countries to facilitate free trade. The U.S. Underwriters
Laboratories (UL) and the Canadian CSA are members of the IEC.
IEEE Institute of Electrical and Electronics Engineers. IEEE (pronounced I-triple-E) is an
organization composed of engineers, scientists, and students. The IEEE is best
known for developing standards for the computer and electronics industry. In
particular, the IEEE 802 standards for local-area networks are widely followed.
IEEE 802.16 Also known as WIMAX. A group of broadband wireless communications standards
for metropolitan area networks (MANs) developed by a working group of the IEEE.
IEEE 802.16e 802.16e, also known as 802.16-2005, is an IEEE standard addressing mobility of
wireless broadband (WiMax). IEEE 802.16e is sometimes called Mobile WiMAX,
after the WiMAX forum for interoperability. 802.16e, based on an existing WiMAX
standard 802.16a, adds WiMAX mobility in the 2-to-6 GHz-licensed bands. 802.16e
allows for fixed wireless and mobile Non Line of Sight (NLOS) applications primarily
by enhancing the OFDMA (Orthogonal Frequency Division Multiple Access).
IEEE 802.1p A QoS method - A three-bit value that can be placed inside an 802.1Q frame tag.
IEEE 802.1q The IEEE 802.1q standard defines the operation of VLAN Bridges that permit the
definition, operation and administration of Virtual LAN topologies within a Bridged
LAN infrastructure. The 802.1q specification establishes a standard method for
inserting VLAN membership information into Ethernet frames. A tag field containing
VLAN (and/or 802.1p priority) information can be inserted into an Ethernet frame,
carrying VLAN membership information.
IEEE 802.3 A Local Area Network protocol suite commonly known as Ethernet. Ethernet uses
Carrier Sense Multiple Access bus with Collision Detection CSMA/CD. This method
allows users to share the network cable. However, only one station can use the
cable at a time. A variety of physical medium dependent protocols are supported.
IF Intermediate Frequency. Radio communications systems modulate a carrier
frequency with a baseband signal in order to achieve radio transmission. In many
cases, the carrier is not modulated directly. Instead, a lower IF signal is modulated
and processed. At a later circuit stage, the IF signal is converted up to the
transmission frequency band.
