Hai

Anybody please say me the Difference between Software timing and hardware timing and it does?

very shortly:

Software timing: Measurement is done in the way, that you use funnction in software to read/write, then the command is sent to the DAQ board, and then operation is performed - board starts AD/DA conversion, for example. It is usefull for slower applications, when you don't need precise timing

Hardware timing: DAQ board is timed by internal HW clock. It means, that all AD/DA conversions run based on hardware clock (very precise compared to software). Measurement is then put directly to buffer buffer, when you generate, you need to prepare data into buffer.
