IANA | The Internet Numbering Address Authority (IANA) is an organization under the Internet Architecture |
| Board (IAB) of the Internet Society that oversees IP address allocation. It is under a contract from the |
| U.S. government. |
ICMP | Internet Control Message Protocol is a protocol used for error, problem, and informational messages |
| sent between IP hosts and gateways. ICMP messages are processed by the IP software and are not |
| usually apparent to the |
ICSA | The International Computer Security Association is the security industry’s main source of research, |
| intelligence, and product certification. |
IEEE | The Institute of Electrical and Electronics Engineers, Inc. (http://www.ieee.org) is an organization that |
| produces standards, technical papers, and symposiums for the electrical and electronic industries and |
| is accredited by ANSI. |
IEEE 802.11b | IEEE wireless network standards. |
IEEE 802.11g |
|
IEEE 802.3 | See Ethernet. |
IETF | The Internet Engineering Task Force (http://www.ietf.org) is an open international community of |
| network designers, operators, vendors, and researchers to develop and maintain Internet architecture. |
| Technical working groups issue working documents called |
| versions of the drafts called requests for comments (RFCs). |
IGMP | Internet Group Membership Protocol the Internet multicasting standard. IGMP establishes and |
| maintains a database of group multicast addresses and interfaces to which a multicast router forwards |
| multicast packets. IGMP runs between multicast hosts and their |
| routers. |
IGMP spoofing | A process where a router acts as an IGMP querier for multicast hosts and an IGMP host to a multicast |
| router. |
impedance | The total opposition to AC electron current flow within a device. Impedance is typically 75 ohms for |
| coax cable and other CATV components. |
impulse noise | Noise of very short in duration, typically of the order of 10 microseconds. It is caused by electrical |
| transients such as voltage spikes, electric motors turning on, and lightning or switching equipment that |
| bleed over to the cable. |
ingress noise | Noise typically caused by discrete frequencies picked up by the cable plant from radio broadcasts or |
| an improperly grounded or shielded home appliance such as a hair dryer. Ingress is the major source |
| of cable system noise. |
Internet | A worldwide collection of interconnected networks using TCP/IP. |
Internetwork | A collection of interconnected networks allowing communication between all devices connected to any |
| network in the collection. |
IP | Internet Protocol is a set of standards that enable different types of computers to communicate with |
| one another and exchange data through the Internet. IP provides the appearance of a single, |
| seamless communication system and makes the Internet a virtual network. |
