i-mode
Proprietary packet-based information service for mobile phones. i-mode delivers information (such as mobile banking, and train timetable) to mobile phones and enables exchange of email from handsets on the PDC-P network. Launched in 1999 by NTT DoCoMo, i-mode is very popular in Japan (especially for email and transfer of icons), but is not currently being used elsewhere.
import
Within the context of an application program, to use a function or data defined in a DLL.
See also: DLL, export
import library

integer editor
A concrete control which supports editing an integer value.
integer range editor
A concrete control which supports editing an integer range value. Has two fields; the second may not be smaller than the first.
interface class
A class that primarily defines a protocol, but does not provide an implementation. This means they only describe the expected behaviour of an object. The use of multiple inheritance is restricted to interface classes.
See also: mixin protocol
internalise
The process of reading data from a stream and assigning the data to an object or constructing an object from the data.
international dialling prefix
The country dependent dialling prefix used to make an international call, e.g. the prefix is 00 in the UK.

interrupt handler
Code that the processor jumps to on receipt of an interrupt request.
interrupt latency
The time between an interrupt going off and the interrupt being serviced by the operating system.
invalid
