| Initialization Files | (1)In Windows,files with the extension.INI. They contain information that defines your Windows environment. (2)CalledINITs on the Macintosh.Files which load when the computer starts up which change the way the computernormally behaves. One INIT allows you to access MS-DOS disks on the Mac. Anothermakes Oscar the Grouch sing whenever you throw trash away. In System7, INITs are called extensions. |

| Intel | Maker of the 80x86and Pentiumlines of processors which are used in IBM PCand compatible computers. |
| interactive fiction | Interactive fiction (often abbreviated "IF" or "I-F") is a form of literature unique to the computer. While the reader cannot influence the direction of a typical story, the reader plays a more active role in an interactive fiction story and completely controls its direction. Interactive fiction works come in all the sizes and genres available to standard fiction, and in fact are not always even fiction per se (interactive tutorials exist and are slowly becoming more common). |
| Interface | Part of a computer, program, or peripheralthat communicates with other components. Interface also refers to the userinterface. |
| Internet | A worldwide collection ofinterconnected networks,providing a wide variety of services, using the TCP/IPnetwork protocols. |
| InterNIC | Internet Network Information Center
|
| interpreted | If a program is interpreted, its actual human-readable source is read as it is run by the computer. This is generally a slower process than if the program being run has already been compiled. |
| Interpreter | A program that readsand executes sourcecode one line at a time. Does not create an executable file that can runindependently. Compare to compiler. |
| Interrupt | On IBM PCand compatible computers. A signal that a devicesends to the computer when the device is ready to accept or send information.See interuptrequest (IRQ). |
| Interrupt Request | On IBM PCand compatible computers. Hardware lines over which devices can send interrupts.Typically each deviceconnected to the computer uses a separate IRQ. It is a good idea to know whichIRQ each device on your computer is using (the IRQ for the mouse and keyboardshould be found in your manuals). Expansioncards such as Ethernet cards or token ring adaptors also use IRQs. Settingthe IRQ so that it does not conflict with (use the same IRQ as) other devices isan essential part of installing expansion cards and new devices. |
| INTO | Interrupt if Overflow occurs
