There is not. And that is because 64bit can run 32bit, but 32bit has problems running 64bit.
64bit
Absolutely !
64bit
64bit processors have most registers specially the integer registers as 64bit. It can handle 64bit wide internal and external data. All internal and external buses may or may not be 64bit wide. - Neeraj Sharma
Yes, but it doesn't work wit 64bit browers like the IE 64bit....
The size of the accumulator is the same,means 64bit.
No
Over the years I have found that computers with 64bit dual or quad core CPU's and a 64bit operating system is best.
No, not unless all of the following .Confirm that the computer's processor and motherboard are both 64bit. All 64bit Windows Operating systems will only work on computers that have both 64bit processor and 64bit motherboard architectures.Confirm the computer has no less then the other minimum hardware requirements (Processor Speed, Ram memory, Hard Drive memory, etc.) for the Windows 7 64bit version you want to install.Windows XP 32bit must be removed/deleted before doing a clean install of Windows 7 64bit on the hard drive.
The difference between 32bit windows and 64bit windows is the resolution of the image and the higher the bit the better the image.
This depends on the laptops CPU.
