IRQ
Abbreviation for 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

devices can share the same IRQ assignment, but you
cannot operate both devices simultaneously.
ISA

expansion bus design. The expansion-card connectors
in an ISA system are also compatible with 8-bit ISA
expansion cards.
ISV
Abbreviation for independent software vendor.
ITE
Abbreviation for information technology equipment.
Java
A cross-platform programming language developed by

JSSE
Abbreviation for Java Secure Socket Extension.
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
