A conceptual question: Text flow, Text Wrap, Textwrapping?

[mtnylmz]

I tried to make a search on the web, but I didn't understand "Text flow" very well. I think text wrap is "wrapping around a picture with a text". Would you please explain "Text flow"? What is the alternative or the opposite feature of it, if any? Page flow?

Probably this is an ordinary and integral feature of all text editors and word processors, but do you know any app that we can write in but has not that feature?

Thank you.

You seem to have done little here to try and research yourself - perhaps a search such as "what is text flow" might help you.
