Virtual memory

This is a 1978  IBM poster explaining Virtual memory which I thought was pretty cool:

If it’s there and you can see it–it’s real

If it’s not there and you can see it –it’s virtual

If it’s there and you can’t see it –it’s transparent

If it’s not there and you can’t see it –you erased it!!
