Solution

Digital I/O VI:

Digital I/O port is the collection of digital lines.

Digital input and output can read or write the lines in entire digital port.

Digital input and output are used to communicate a true or false or zeros and ones.

Digital I/O is the basics of computer technology.

Digital input is used to trigger the acquisition of the signals.

Digital output is often used to indicate that if threshold has passed or if power is applied to circuit.

Time Delay VI:

Time delay explains that how many second to wait or how many second delay running the calling VI.

The default value is 1.

Generally it is used to know that how much time delay running the calling VI.

Flat sequence structure:

In flat sequence structure executes from left to right.

When the data wired to frame is available.

When the data leaves in each frame after finishes the executing.

This shows that input of one frame depends on output of other frames.

The use of flat sequence structure is it displays the each frame on block diagram.

If we add or delete the frames ,it automatically resizes the structure.

Stacked sequence Structure:

In stacked sequence structure each frame executes one frame after another.

It gives or returns data after the execution of last frame.

The use of stacked sequence is to conserve space in the block diagram.

While loop:

The while loop executes until the conditional terminal receives a particular boolean value.

While loops executes sub diagram until a given condition occurs.

While loop runs infinite times if the condition never occurs.
