I/O
input/output. The keyboard is an input device and a printer is an output device. In general, I/O activity can be differentiated from computational
activity. For example, when a program sends a document to the printer, it is engaging in output activity; when the program sorts a list of terms, it is
engaging in computational activity.
ID

interlacing
A technique for increasing video resolution by only updating alternate horizontal lines on the screen. Because interlacing can result in noticeable
screen flicker, most users prefer noninterlaced video adapter resolutions.
internal microprocessor cache
An instruction and data cache built into the microprocessor. The Intel Pentium microprocessor, for example, includes a 16-KB internal cache,
which is set up as an 8-KB read-only instruction cache and an 8-KB read/write data cache.

IRQ
interrupt request. A signal that data is about to be sent to or received by a peripheral device travels by an IRQ line to the microprocessor. Each
peripheral connection must be assigned an IRQ number. For example, the first serial port in your computer (COM1) is assigned to IRQ4 by default.
Two devices can share the same IRQ assignment, but you cannot operate both devices simultaneously.
ISA
Industry-Standard Architecture. A 16-bit expansion bus design. The expansion-card connectors in an ISA computer are also compatible with 8-bit
ISA expansion cards.
ITE
information technology equipment
J
jumper
Jumpers are small blocks on a circuit board with two or more pins emerging from them. Plastic plugs containing a wire fit down over the pins. The
wire connects the pins and creates a circuit. Jumpers provide a simple and reversible method of changing the circuitry in a printed circuit board.
