64-bit, 32-bit, 2008 , 2008r2

[Sher]

Hi all,
I am really confused right now:
Is server 2008 32-bit or 64-bit OS?
Is server 2008 R2 64-bit OS?
Will 32-bit software run on a 64-bit OS machine?
Right now I only have 32-bit software running but I never know when the
vendor's upgrades might require 64-bit. So which new server OS is best to go
with.
We normally keep our servers a long time (I have one that is 10 years old).
I only get to buy once in a blue moon so I need to make the right choice.
I also need to make sure my 32-bit programs will still function.

thanks in advance for any help.
Sher

You can use both flavors of it. There's 32bit and 64bit SErver 2008. If
you're on 64bit hardware, I'd go 64bit Windows.

Yes. There's no 32bit version of Server 2008R2.

Yes.

Current hardware works best with 64bit Windows. Once the vendors compile
their software to support 64 bits, you can install that on the machines.

64bit is the future. You won't be able to upgrade a 32bit version of
Windows to a 64bit version -- so I'd go for 64bit.

32bit is so last century -)
