    64-bit is also faster due to the way the code is executed. This is mainly for 64-bit applications running under 64-bit Windows, but 32-bit applications can also benefit.

    Just for information:
    On typical PC's, 32-bit is commonly referred to as x86, and 64-bit as x64. There are different architectures for x86 and x64, its only the 'x86 based' ones that are applicable to Windows and general computing. 64-bit (x64) can also be referred to as AMD64, since x64 is AMD's 'invention'. You will find that on the installation disk for Windows, the 64-bit folder is referred to by 'AMD64'. There is also IA64 64-bit which is only for Itanium platforms, and is being phased out.

    The long form for x86 and x64 can be described as x86-32, and x86-64, since both are x86 based.
