my home PC is a 32 bit, but the computer in my cubicle at work is 64 bit. I was never really able to tell the difference, possibly due to my ignorance with the intricacies of computers, so can someone explain it to me?
32 bit can only support up to 4 gigs of ram, with applications only being able to use 3 gigs of it at most. 32 bit also has more compatibility with older 16 bit programs like old games released in the 90s and such. 64 bit supports more than 4 gigs of ram, and applications can use as much ram as needed. However, 64 bit isn't compatible with older 16 bit applications. Someone else would be able to explain it better than I can.

That is somewhat incorrect. You only use about 4GB of RAM no matter what. The RAM chooses you.
I read somewhere that 32 bit operating systems have a "code" (bits?). Each code can do whatever it wants, but it can only limit it's power by 32 bits, per "string" if you think of this as a string process. 64 bit operating systems can carry twice as much data. Though this is only noticeable with 4Gb of RAM or more, making a truly faster operating system, processing bits per 64 in length. This also can make you do more than one think more efficiently.
This wasn't the best explanation but it should give an idea.
x86 can only allocate 4GB of ram, x64 can allocate a lot more.
There you go.

Just use Dosbox for 16-bit applications, Windows' "native" support for them sucked anyways.

How much actually?
Something much higher than the 256GB cap that is built into Windows 64bit versions is all I know. For all intents and purposes, it's practically unlimited.

Funfact: They up that limit every time a computer is made with more. They put that cap on there because that's as high as they were able to test it at.

What kind of crazy server supports 2TB of ram?

:iiam:

2^64 =~ 1.845 * 10^19
But its gonna be a long time before computers have that much ram

Probably can only do it if you have one of those 5,000 dollar expensive fucked up server motherboards.

They probably rented time at a Supercomputer to do that.
Supposedly the IBM Roadrunner has 8 TB of RAM, along with 2 PB of external storage...

Sorry for the dumb question, but what kind of RAM is that?
x86 (32bit) OS without PAE-Support (such as x32 Windows Versions) can only address 2^32 addresses.
This means, the maximal amount of RAM it can allocate is "4 GB - all other previous registers (such as GFAX-Card ram)".
x86 (32bit) OS with PAE-Support on an PAE-Enabled motherboard (nearly all "non-ultra-cheap" MB support PAE) can address 2^36 addresses (64 GB).
x64 (64bit) OS can even addresse 2^64 addresses which is a shitload more. But especially MS Windows caps this to a limit based on the license you have (which is still much more than the 4GB limit on x86 Windows OS of 4 GB).
Anyway: It make no sense not using x64 on a x64 capable machine - even if you have less ram than 4 GB. The 64-bit-change has began years ago.
Anyone find a computer with an exabyte of storage?

Or zetta
[editline]03:14PM[/editline]
Or yotta
[editline]03:15PM[/editline]
Or all of those together
you know every step you go up and it becomes exponentially unlikely that so much storage space exists.
Window 7 is locked at 128Gb RAM, but in theory 64-bit supports, well infinite.

2^64 is not infinite.

No but we aren't going to hit 16EiB of RAM in a very long time.

Give IBM a few months and they'll do it. :v:

I thought you meant HP had a 128GB limit, I'm stupid, sorry.
