  • 1) See http://en.wikipedia.org/wiki/64-bit for an intro and links

    2) The OS is split in user-mode and kernel mode and code can run in both. Apps typically run in user mode and OS components typically run in kernel mode. Drivers can run in both. IIS as an example has the HTTP listener implemented as a kernel mode driver but the worker process runs in user mode. See this link about different driver types, driver SDKs, certification of drivers etc: http://www.microsoft.com/whdc/driver/foundation/default.mspx
