The National Instruments software for GPIB systems

NI-DAQ

The National Instruments software for data acquisition instruments

NI-VISA

The National Instruments implementation of the VISA standard; an 
interface-independent software that provides a unified programming 
interface for VXI, GPIB, and serial instruments

NMI

Non-maskable interrupt; high-priority interrupt that cannot be disabled by 
another interrupt. It is used to report malfunctions such as parity, bus and 
math coprocessor errors.

PCI

Peripheral Component Interconnect. The PCI bus is a high-performance 
32-bit or 64-bit bus with multiplexed address and data lines.

PCMCIA

printer, plotter, disk or tape drive, graphics tablet, scanner, mouse, and so on

POSC

Power On Self Configuration

PXI

PCI eXtensions for Instrumentation; an open implementation of 
CompactPCI that adds electrical features that meet the high-performance 
requirements of instrumentation applications by providing triggering, local 
buses, and system clock capabilities. PXI also offers two-way 
interoperability with CompactPCI products.

RAM

Random Access Memory; the computer’s primary workspace

RAMDAC

Random Access Memory Digital to Analog Converter; the VGA controller 
chip that maintains the color palette and converts data from memory into 
analog signals for the monitor

resource

hardware settings used by devices in a computer system, including ISA 
interrupt level, DMA channel, and I/O address
