(doesn't "virtual" stand for "swap"?).
No, virtual memory is just none linear memory,
if memory looks like this on classic system:
ooo***ooo****ooooo**
'o' is free RAM, and '*' is Used.
if you need 6 blocks or 'oooooo' you where not able to find memory needed on AmigaOS3 becouse larges memory is 5 blocks only, but on AmigaOS4.0, can reorganize memory so that all free blocks can be used.
Swap is used when you run out free RAM, in this state AmigaOS3 crashes or programs stops working, but on on AmigaOS4 frees memory by moving Virtual memory to SWAP when needed.
Where few programs uses virtual memory, it can be where useful if not misused.
