I've heard of the concept of "sending" and "receiving" data via an API. "Consuming" data would be "receiving" the data. In terms of "consuming" data, what would be its corresponding opposite term?
Serving
Think of it as the API as a waiter serving your meal, and you consuming it.
In this article the authors use serving as an opposite to consuming: https://stackoverflow.blog/2020/03/02/best-practices-for-rest-api-design/

I'd love to know/see some example code from the lowest level. By this I mean the code that for example, sets the voltage to the speakers, or something equivalent. I can't imagine how this would look/work.
How could a piece of code possibly set/change a physical quantity? I'm not looking for some driver code, but the actual code that makes hardware 'work', or does it work in a different way?

I am hoping this is a easy question to answer. Default recovery file disk location and the size set for your recovery area
Always include Oracle version and platform.
You should check v$flash_recovery_area_usage and v$recovery_file_dest
Hope that helps.
