IDE

The integrated drive electronics (IDE) is a common x86 based interface.

Incremental Dump

An incremental dump saves all data created or modified since the previous dump was performed; incremental dumps are performed more frequently than full dumps.

Indirect Block

Indirect block addressing as used in UNIX systems is an inode field which points to other inode blocks instead of user data. This is as opposed to direct block addressing, which points to a block containing the file.

Inode

An inode is an entry in a predesignated area of the disk that describes where a file is located on that disk, the size of the file, when it was last used, and other identification information.

Input

Input is any information provided to a command, a program, a terminal, a person, and so on.

Instance

In the context of the kernel, when referring to a disk device name, each use of a device identifier (for example, sd0) is considered an instance of that device type.

Internet

The Internet is the largest network in the world. It consists of a large national backbone network which contains the Military Network (MILNET), the National Science Foundation Network (NSFNET), and the European Laboratory for Particle Physics (CREN), and a myriad of regional and local campus networks all over the world. To be able to log on the Internet the user must have Internet protocol (IP) connectivity; that is, be able to communicate with other systems by using telnet or ping. Networks with only email connectivity are not classified as being on the Internet.

Internet Address

An IP address is a 32-bit unsigned integer used by networking software to uniquely identify machines attached to the network.

IPI

The Intelligent peripheral interface (IPI) device is the SPARC(R) system interface.
