Glossary
PCMCIA
an expansion bus architecture that has found widespread acceptance as a de 
facto standard in notebook-size computers. It originated as a specification 
for add-on memory cards written by the Personal Computer Memory Card 
International Association.
PFI
programmable function input
Plug and Play devices
devices that do not require dip switches or jumpers to configure resources 
on the devices—also called switchless devices
Plug and Play ISA
a specification prepared by Microsoft, Intel, and other PC-related 
companies that result in PCs with plug-in boards that can be fully 
configured in software, without jumpers or switches on the boards

samples after trigger conditions are met
pts
points
R
RAM
random-access memory
real time

instead of being accumulated and processed at a later time
REQ

grounded measurement system.
RTSI bus
real-time system integration bus—the National Instruments timing bus that 
connects DAQ boards directly, by means of connectors on top of the boards, 
for precise synchronization of functions
