That's correct, it will vary, based on system configuration, but the numbers
won't be that different. And yes, it all adds (system RAM, graphics card
RAM, etc.).

LL: allow me to give a simple example of why the 32-bit OS just can't
utilize all 4GB of RAM.
Let's stick with decimal numbers (because most of us think better in decimal
than binary or hexadecimal), and let's keep it simple:
Let's say I have 4 digits available, How high can I count? Right: 9999 is
the biggest number I can represent with just four digits. So what if I want
to count to one million? Well, I can't - unless I get more digits, right?
In a simplistic way, this is the basic issue with the 32-bit OS vs the
64-bit OS. with 32-bits I can only go up to approx 4 billion. If I get more
digits - 64 bits - I can count higher.
I hope this is helpful, and that I didn't make you read it for nothing...

Bob, it is NOT 3.12GB. You are not reading the article carefully. That

just a number the author pulled out of the air as an example. The range
across computers is from as little as 2GB to 3.5GB or so.

For all practical purposes there is a 3.12GB limit on a 32-bit
system.

On my 32 bit system with 4 GB, I get 3.325 GB of the 4 GB from the
physical memory. Each 32 bit system will be slightly different depending
on configuration.
