64 Bit CPU and 32Bit OS/Apps

[Willz]

Hi, I know the answer, but just to clafiry it for some other people.

Is it true that a 64Bit CPU can:

1: Run a 32bit Operating System
2: Run a 32bit applications
3:In a 64Bit OS such as Windows XP 64Bit, 32apps are ran in some sort of subsystem?

4: Also Its illigal for Microsoft to take over someone computer right?

1+2: yes, you can run 32-bit OS and software on a 64-bit system.
3: I dunno
4: Yeah I think so. But no big companies would take any action, because M$ has the money for a good lawyer.

A 64-bit CPU can run 32-bit apps in either hardware, with 32-bit hardware support, or through software support, if the CPU is exclusively 64-bit, like Intel's Itainium.

The x86-64 bit CPU's from Intel and AMD are 32-bit and 64-bit simutaneously in the hardware itself.

Microsoft takes over someone computer=Hacking>Hacking=illegal.

Im sure that the obove statement would hold true in any court of law. I think:)

Yes you can.

3:In a 64Bit OS such as Windows XP 64Bit, 32apps are ran in some sort of subsystem?

I think so, because most of the chat system used still used lower bit rate.

4: Also Its illigal for Microsoft to take over someone computer right?

Its illigal. But most of the compay not get any legal action against you because all the stuff like hacking point out new requirment on security, etc

Most of the countries don't have any rules to govern illegal IT related resources. That's why there people sold WinXP Pro around half a dollar.
