  2. I/O request packet - Wikipedia

    en.wikipedia.org/wiki/I/O_request_packet

    I/O request packets (IRPs) are kernel mode structures that are used by Windows Driver Model (WDM) and Windows NT device drivers to communicate with each other and with the operating system. They are data structures that describe I/O requests, and can be equally well thought of as "I/O request descriptors" or similar.

    If this thread is the one that handles the data after the I/O request completes, then a thread-switch, which causes a performance hit, may be avoided. Windows Vista also introduces synchronous I/O cancellation. During a synchronous I/O request, the application is blocked until the request is serviced or fails.

  4. Input/output completion port - Wikipedia

    en.wikipedia.org/wiki/Input/output_completion_port

    When I/O services are requested on the object, completion is indicated by a message queued to the I/O completion port. A process requesting I/O services is not notified of completion of the I/O services, but instead checks the I/O completion port's message queue to determine the status of its I/O requests.

  6. INT 13H - Wikipedia

    en.wikipedia.org/wiki/INT_13H

    Under protected mode operating systems, such as Microsoft Windows NT derivatives (e.g. NT4, 2000, XP, and Server 2003) and Linux with dosemu, the OS intercepts the call and passes it to the operating system's native disk I/O mechanism. Windows 9x and Windows for Workgroups 3.11 also bypass BIOS routines when using 32-bit Disk Access.

  7. Input/Output Supervisor - Wikipedia

    en.wikipedia.org/wiki/Input/Output_Supervisor

    The Input/Output Supervisor (IOS) [1] is that portion of the control program in the IBM mainframe OS/360 operating system and successors which issues the privileged I/O instructions and supervises the resulting I/O interruptions for any program which requests I/O device operations until the normal or abnormal conclusion of those operations.

  8. Windows Driver Model - Wikipedia

    en.wikipedia.org/wiki/Windows_Driver_Model

    In computing, the Windows Driver Model (WDM) – also known at one point as the Win32 Driver Model – is a framework for device drivers that was introduced with Windows 98 and Windows 2000 to replace VxD, which was used on older versions of Windows such as Windows 95 and Windows 3.1, as well as the Windows NT Driver Model.

  9. Windows 9x - Wikipedia

    en.wikipedia.org/wiki/Windows_9x

    Device drivers in Windows 9x can be virtual device drivers or (starting with Windows 98) WDM drivers. VxDs usually have the filename extension.vxd or .386, whereas WDM compatible drivers usually use the extension .sys. The 32-bit VxD message server (msgsrv32) is a program that is able to load virtual device drivers (VxDs) at startup and then ...
