What is the difference between a Zener diode and a switching diode?

Unsolved

Recently I am learning Zener diode and I think it’s a little difficult for me. I read many articles on the Internet, and they helped me a lot, like The Working Principle of the Zener Diode and the Judgment of the Positive And Negative Poles.

However, I still can’t figure out the differences between Zener diode and switching diode.

So if you have any good passages or websites about it , could you please share them to me?

Thanks a lot.
