Well I guess I should rephrase...
It is seen as another block device to the OS, Windows, Linux or what have
you.
So, in Windows it would be a drive letter.
In Linux it would be a block device that you could partition and format.
I have not personally used it, but, there are folks out there

Yes, but, old school ramdisks (i.e. creating disks in existing RAM),
aren't exactly reliable if something goes wrong (i.e. power anomalies, bad
memory block, etc.). So whatever you would be storing would have to be
temporary (which I guess you have already said), AND, you would have to NOT
care

JSON is just another data exchange format like, csv, xml, etc.
The main advantage is that it is arguably better at passing name, valued
pairs of data (like Pick/MV in DataBASIC), than xml, etc.
It can also arguably make writing AJAX (i.e. FAST data entry web forms),
somewhat easier (with
typed and fairly compact, so a perfect fit for MV programmers and
data.

+1 for what David said. Yes, there's the limitation that BASIC is the
