From: Joe Buck <buck@nrl-css> Mr. Wood says that paging is only one way of implementing virtual memory (so paging != virtual memory). Maybe so. But the question came up originally in the context of a comparison between bsd4.X and System V on VAXes, and it appears to me that he is attempting to defend the system V scheme. By currently accepted definitions, however, the swapping system implemented by BTL for System V on VAXes is NOT virtual memory, but this is a matter of semantics. The central point is that the System V memory management scheme is inferior and wastes one of the best features of the VAX, which is why most VAX sites will continue to use bsd, despite other problems with Berkeley.
