sizes of RAM, of virtual memory and of swap for 32-bit OS
- by Tim
If I understand correctly, a 32-bit OS (Ubuntu) can only address 4GiB memory, so RAM with size larger than 4Gib will only be used 4Gib of itself and the rest is a waste.
I am now confused about this situation for RAM with similar one for virtual memory and for swap.
with virtual memory being swap +
RAM, if the size of the virtual
memory exceeds 4Gib, will the
exceeding part be a waste for the
32-bit OS?
if I now have to choose the size for
my swap partition, is it a factor to
consider that the 32-bit OS can only
address 4GiB memory? Does the size
of swap have to be chosen with
respect to the 4Gib addressible
limitation? Will the swap exceeding 4GiB always be a waste?
is virtual memory equal to RAM and
swap? or can virtual memory use
space on the hard drive outside the
swap partition?
Thanks and regards!
