VISA -- What is it and is it part of the LabView Program Package

I am relatively new to Labview. I have taken the Basic I & II courses offered
by the National Instruments and want to take other courses. I have looked
through the manuals and all and ran a few of the programs but am not sure what
VISA is... Is it an integral part of the LabView package and what is it used
for????

Answers:
1) The Virtual Instrument Software Architecture (VISA) is a comprehensive
package for configuring, programming and troubleshooting instrumentation
systems comprised of VXI, VME, PXI, GPIB, and/or serial interfaces.

For more info, check out http://www.ni.com/visa/

2) No, VISA is a seperate.

3) VISA is used for communication. VIs written with VISA do not have to
be re-written if the communication style changes (ie going from GPIB to VXI).

I hope that this helps,

NI-VISA is included with LabVIEW on every (I believe) platform that LabVIEW
ships on. Most of the core VISA functions are primitives in LabVIEW, giving
LabVIEW oriented graphical elements (like property nodes) for VISA concepts
(like attributes). That's about as integrated as you can get.

is a good place to start.
