I-K
IEEE 1394
A standard for high-speed serial devices such as digital video and digital audio editing equipment.
image
A collection of files and folders (sometimes compressed into one file) that duplicates the original file and folder structure of an operating system. It often contains other files added by the OEM or corporation.
Integrated Services Digital Network (ISDN)
A digital phone line used to provide higher bandwidth. ISDN in North America is typically available in two forms: Basic Rate Interface (BRI) consists of 2 B-channels at 64 kilobits per second (Kbps) and a D-channel at 16 Kbps; Primary Rate Interface (PRI) consists of 23 B-channels at 64 Kbps and a D-channel at 64 Kbps. An ISDN line must be installed by the phone company at both the calling site and the called site.
Internetwork Packet Exchange (IPX)
A network protocol native to NetWare that controls addressing and routing of packets within and between local area networks (LANs). IPX does not guarantee that a message will be complete (no lost packets).See also local area network (LAN).
Intersite Topology Generator
An Active Directory process that runs on one domain controller in a site that considers the cost of intersite connections, checks if previously available domain controllers are no longer available, and checks if new domain controllers have been added. The Knowledge Consistency Checker (KCC) process then updates the intersite replication topology accordingly.See also domain controller.See also replication topology.See also site.
IP address
For Internet Protocol version 4 (IPv4), a 32-bit address used to identify an interface on a node on an IPv4 internetwork. Each interface on the IP internetwork must be assigned a unique IPv4 address, which is made up of the network ID, plus a unique host ID. This address is typically represented with the decimal value of each octet separated by a period (for example, 192.168.7.27). You can configure the IP address statically or dynamically by using Dynamic Host Configuration Protocol (DHCP).For Internet Protocol version 6 (IPv6), an identifier that is assigned at the IPv6 layer to an interface or set of interfaces and that can be used as the source or destination of IPv6 packets.See also Dynamic Host Configuration Protocol (DHCP).See also node.
