Hi

I'd like to know what Windows XP (x86) and Windows XP (x64) are?
I use Windows XP, but I don't know which one I use.
How do I know?



x86 is 32-bit Windows, and x64 is 64-bit Windows.

The answer, for almost everyone who has to ask, is that you using
32-bit (x86).


For the curious: x86 is a reference to the x86 series of processors
which
started with the intel 8086 processor (which was a 16 bit processor and
wouldn't be able to run a 32 bit operating system).


And interestingly was never used in a PC. The first PC used an 8088
instead.

Pretty similar, though. :-)
It's been awhile, though, and I can't remember the difference between the
8088 and 8086 anymore.


The major difference is that the 8088 was 8-bit and the 8086 16-bit.


I seem to remember 20-bit *addressing*, and a 16
bit word size for the *data* bus.

That's what I said too. But there was a notable difference between the
two, and maybe the 8088 only had a 8 bit *data* bus.
