And yes , does the computer 's memory fill up at the same time ? I didn't and didn't understand

Answer 1

Notion stores files online in Amazon Web Services. This may change to other providers, but to answer your question everything is online.

If you upload an image to Notion and delete it from your computer, then the image is in the cloud and not in your computer unless you download it again.
