how to work out a page size?

[looney]

Need some help on this. How do I work out the size of a page in a system? and the size of the address space of a process?

heres an example:

Processor A uses 32bit address with a 20 bit page number and a 12 bit offset.

How do go abouts to doing this?


thanks in advance

The Windows paging file is virtual memory, it doesn't exist in the physical memory address space, other than a file descriptor and a pointer. If it did, that would defeat the purpose of freeing up memory resources. Just set it to the RAM-total amount you *need*. If you never use more than 4GB, then disable swap entirely.
