- Wide area network. A communications network that connects geographically
separated areas. Compare with LAN.
- warm docking
- A method of removing or installing a mobile system in a docking station
with which the computer can be docked or undocked while in a reduced power
state, such as suspend.
- Web-based Enterprise Management. Technology under development by BMC
Software, Inc., Cisco Systems, Inc., Compaq Computer Corporation, Intel
Corporation, and Microsoft Corporation, based on standards being developed by
DMTF and IETF, to provide a mechanism to specify information exchange between
management applications and managed components.
- Windows Driver Library. See WHQL.
- Windows Driver Model. A driver model based on the Windows NT/Windows
2000 32-bit driver model that is designed to provide a common architecture of
I/O services and binary-compatible device drivers for both
Windows NT/Windows 2000 and Windows operating systems for specific
classes of drivers. These driver classes include USB and IEEE 1394 buses,
audio, still-image capture, video capture, and HID-compliant devices such as
USB mice, keyboards, and joysticks. Provides a model for writing kernel-mode
drivers and minidrivers, and provides extensions for Plug and Play and power
- WDM DDK
- Provides the supplementary header files used together with the
Windows 2000 DDK to build WDM drivers.
- WDM power management
- Facilities provided in WDM for drivers to implement power policy and
control. DDIs are defined for synchronizing power state changes with other
power management activities in the system and for detecting device idleness.
IRPs are defined for setting power sate, enabling wakeup, and querying power
- WDM streaming
- A WDM-based kernel-mode extension of Microsoft ActiveMovie, providing
kernel connection and streaming services as used by the WDM Stream class
driver and system software components provided in future versions of the
Windows and Windows NT/Windows 2000 operating system, such as the
cross-process audio mixer and sample rate converter. WDM streaming provides
low-level services for the lowest latency streaming; ActiveMovie provides
higher-level features. Operating system support includes a Stream class driver
that supports minidrivers for audio, video, and other types of stream input,
output, and acceleration.
- Windows Hardware Quality Labs. Formerly Microsoft Compatibility Labs.
Provides compatibility testing services to test hardware and drivers for
Windows and Windows NT/Windows 2000. Administers testing for the
"Designed for Microsoft Windows" logo programs. Information:
- Win32 API
- A 32-bit application programming interface for both Windows and
Windows NT/Windows 2000 that includes sophisticated operating-system
capabilities, security, and API routines for Windows-based applications.
- Refers to the Microsoft Windows 95 operating system, including any
add-on capabilities and any later versions of the operating system.
- Windows NT
- Refers to the Microsoft Windows NT version 4.0 operating system,
including any add-on capabilities, unless specific design issues are defined
that relate to Microsoft Windows 2000.
- Windows 2000 DDK
- Supports Windows 2000, provided through MSDN Professional membership.
Documents the Windows 2000 driver model (upon which WDM is based) and is
an essential component for building WDM drivers.
- Windows 2000 driver
- The layered device driver model used under the Windows 2000 operating
system. For information, see Inside Windows NT, by Helen Custer
(Microsoft Press, 1993).
- Windows Management Instrumentation. Extensions to WDM being developed for
Windows 2000 and Windows 98 to provide an operating system interface
through which instrumented components can provide information and
- In general, a powerful computer with considerable calculating and graphics
