Re: Windows 7 32 bit or 64 bit

32 vs. 64 bit has to do with the way the computer physically addresses the data; literally 32 or 64 pieces of information at a time (specifically that many ones or zeros at a time-- that's what a "bit" is, a one or a zero in binary computing. Multiple bits comprise a byte. Enough bytes make a "k", then megs, gigs, etc.)

You must run the correct bit OS on the appropriate processor. Applications vary. You can run some 32 bit applications on some 64 bit machines which I assume requires some sort of emulation mode by the OS which may be transparent to the user. 64 bit applications won't work for 32 bit.

JAWS 9 was 32 bit only. At the time that was out, Freedom told me they had no intention of supporting 64 bit machines in the future. Once most new machines started going 32 bit, they changed their tune a bit. (Pun intended.)

I assume current JAWS has a dual installer that works on both? I know both are currently supported one way or another.

Hi,
I have Jaws 12, but have reverted to Jaws 11 as 12 was crashing too often.

I'm afraid I need to think seriously about a new computer.

I'm still with XP Home.

Can someone tell me what would be the major difference between Windows 7 32 bit or 64 bit?

Thanks.
Crystal
