Potentially the data path could be 64bits which would double the
peripheral data transfer rates. However it is my understanding that
present '64 bit' motherboards have a 32 bit wide data path due to chip
limitations. I think I read that somewhere.

Well, they can't *manipulate* it, they can only *address* it, that is,
use bits of it. But the underlying 64 bit OS can address more, so it can
keep more that 4GB of 32 bit apps in RAM, thereby making it a lot faster
to switch. A 32 bit OS can keep less than 4GB of apps in RAM. However I
think that more than 4GB of 32 bit apps is a bit of a stretch, I'll give
you that.

Cheers,

Cliff

how many desktop applications do you need to have running at the same time that would cause you to
require 12gb of RAM installed just to use your desktop computer normally?

But what if you don't WANT to have them installed?

Then dont use internet explorer on windows.

Why does it matter if you install them or not?

Adobe products will use whatever you have and then some

Well, I suppose if you're using Photoshop to produce a poster 4m high x 12m long then you'll certainly
need all the RAM available. but you'd be unlikely to be running anything else on that computer at the
time, and you'd be unlikely to be doing that on a home computer - more likely on a work computer, and
more likely on a Mac.

I'm talking about not wanting _32bit compatible libraries_ installed. Do Windows admins not have the
option of not installing those?

(We often get this 64 vs. 32 bit argument in nz.comp, and I've not
seen this point raised here, so I'm leaping in with it somewhat
arbitrarily here.)

Using a large address space, much larger than the hardware addressable
memory, can be used for different programming paradigms. An early
such approach was mapping files (f.ex. mmap) instead of the open,
read, write stuff, and another doing communication that way. Later,
one maps resources on the internet into one's address space. Let the
OS worry about protocols and APIs and security, just do stuff with
memory, or some abstraction like objects. Or, imagine a functional,
lazy evaluation view of the universe.

It's not necessarily a better way, and it can break the Unix
everything-is-a-file concept. But, for some applications, it can be
vastly simplifying, and for some IO bound tasks getting the virtual
memory system to do all the IO makes them much faster.

I'm sure there's much more eloquent and useful descriptions of these
ideas around, this is off the top of my head. I suppose only big
servers use these approaches presently, and I suppose not many of them
use 32 bit addressing.

Regards, John

That was my point, at the end. I don't know what the OP wants to keep in
his 12GB RAM. XP (32 bit) will happily run a few like IE and Flash
Player in a couple of GB without swapping.

Cheers,

Cliff
