LabVIEW is an acronym of Laboratory Virtual Instrumentation Engineering Workbench. Their appearance and operations resembles real world instruments, such as button, voltmeter, oscilloscope, etc,. and hence they are called as Virtual Instruments (VIs). It offers a graphical programming approach and helps to simulate real world products, which helps you to visualize and program. Thus it requires only logic to program and it is syntax independent. LabVIEW is a high level design tool. It is an interpreter programming (i.e.,) we need not compile it. It compiles itself, we only need to execute it.
