    I am confusion about 32bit and 64bit OS.

    Could anyone inform me about their different?

    If using 64bit OS (Win7), does it similar to Mac OS X that auto switch to
    support 32bit and 64bit device driver?

    I mean can I install 32bit device driver into 64bit Win7 ?

    64bit Win7 requires that your hardware has 64 bit drivers
    You can use 64 or 32 bit programs, eg MS Office is currently only 32bit
    Generally a 32bit driver wont work.
    Win7, depending on version, I believe, has a winxp compatibility mode for
    older software

    The 32-bit /64-bit description refers to the hardware's word length.
    Having a longer word means, among other things, that there is more
    address space. So a 64-bit machine can use more RAM than a 32-bit one.
    Not just twice as much, but many, many times as much.
    Not sure just what OSX does. A 64-bit machine can run either 32-bit or
    64-bit software. (A 32-bit machine can run only 32-bit software, of
    course). There are *many* 64-bit computers running 32-bit Windows. The
    64-bit Windows systems will run 32-bit programs just fine. They will
    not run any 16-bit software that you may still have around.
    No. You have to have 64-bit drivers for the 64-bit OS.
