Is virtual memory measured in terms of the size of pagefile.sys file?

No.
Virtual address space is 2GB on 32 bit, many hundreds of TB on 64 bit. Commitable virtual memory is physical memory + page file size.

It's complex, there's a couple of videos I can find if you want on memory management in windows. What's the problem you're trying to solve?

I'm just trying to understand the memory management in windows.
I'd really appreciate if you can guide me to those videos.

Took me about 3 viewings to get to the point I kinda understood things. Windows memory management is not simple.
