Exactly what is the role of the zero-order hold in a hybrid analog/digital sampled-data system?

I'll admit, I am asking this question rhetorically. I am curious what answers will come back out of this. If you choose to answer this, make sure you understand the Shannon-Nyquist sampling theorem ...

Zero-order hold discretization?

I have some difficulties understanding something. There are several discretization methods, such as zero-order-hold (ZOH), forward euler, backward euler, tustin, et cetera. Forward euler, backward ...
