what is difference between website cache and indexing?

Indexing- Google visited your website and has added you to its database.
Caching- Google toook a snapshot of your website when it last visited and stored the data in case your website went down or if there are some any other issues.

When search engine bots visit on website and add the website to database it's indexing.
when search bots took snapshot of website when it last visited and store the data in our database that's caching.

I think google crawler your pages that is cache and indexing means your page filtering.
