IETFInternet Engineering
Task Force. Task force consisting
of over 80 working groups responsible for developing Internet
standards. The IETF operates under the auspices of ISOC. |
IGMPInternet Group
Management Protocol. Used by IP
hosts to report their multicast group memberships to an adjacent
multicast router. |
IGPInterior Gateway
Protocol. Internet protocol used
to exchange routing information within an autonomous system.
Examples of common Internet IGPs include IGRP, OSPF, and RIP. |
IGRPInterior Gateway Routing
Protocol. IGP developed by Cisco
to address the problems associated with routing in large,
heterogeneous networks. |
infraredElectromagnetic waves whose frequency
range is above that of microwaves, but below that of the visible
spectrum. LAN systems based on this technology represent an emerging
technology. |
interface1. Connection between two systems or
devices. 2. In routing terminology, a network connection. 3. In telephony, a shared boundary defined by common physical interconnection characteristics, signal characteristics, and meanings of interchanged signals. 4. The boundary between adjacent layers of the OSI model. |
IPInternet Protocol.
Network layer protocol in the TCP/IP stack offering a connectionless
internetwork service. IP provides features for addressing,
type-of-service specification, fragmentation and reassembly, and
security. Documented in RFC 791. | |
IP address1.) 32-bit address assigned to hosts
using TCP/IP. An IP address belongs to one of five classes (A, B, C,
D, or E) and is written as 4 octets separated with periods (dotted
decimal format). Each address consists of a network number, an
optional subnetwork number, and a host number. The network and
subnetwork numbers together are used for routing, while the host
number is used to address an individual host within the network or
subnetwork. A subnet mask is used to extract network and subnetwork
information from the IP address. Also called an Internet address.
2.) Command used to establish the logical network address of this
interface. | |
IP multicastRouting technique that allows IP
traffic to be propagated from one source to a number of destinations
or from many sources to many destinations. Rather than sending one
packet to each destination, one packet is sent to a multicast group
identified by a single IP destination group address |
IPXInternetwork Packet
Exchange. NetWare network layer
(Layer 3) protocol used for transferring data from servers to
workstations. IPX is similar to IP and XNS. | |
IS-ISIntermediate
System-to-Intermediate System.
OSI link-state hierarchical routing protocol based on DECnet Phase V
routing whereby ISs (routers) exchange routing information based on
a single metric to determine network topology. |
ISDNIntegrated Services
Digital Network. Communication
protocol, offered by telephone companies, that permits telephone
networks to carry data, voice, and other source traffic |
ISOInternational
Organization for Standardization.
International organization that is responsible for a wide range of
standards, including those relevant to networking. ISO developed the
OSI reference model, a popular networking reference model. |

jitterAnalog communication line
distortion caused by the variation of a signal from its
reference timing positions. Jitter can cause data loss,
particularly at high speeds. |
jumper1.)Term used for patchcords
found in a wiring closet. 2.)Electrical switch consisting of a number of pins and a connector that can be attached to the pins in a variety of different ways. Different circuits are created by attaching the connector to different pins. | |

KBpskilobytes per
second. | |
Keepalive internalPeriod of time
between each keepalive message sent by a network device. | |
Keepalive messageMessage sent by one
network device to inform another network device that the
virtual circuit between the two is still active. | |
