What can virtual memory do for you if you have a 32-bit ISA and 8GB of physical memory? A. Nothing: a 32-bit ISA can only access 4GB of memory B. Not needed: a 32-bit ISA can have multiple programs access more than 4GB of memory without needing virtual memory C. A little: you can use the physical memory beyond 4GB instead of paging to disk for a single application D. A lot: you need virtual memory to have multiple 32-bit applications use more than 4GB of memory together
