Because They Are Part of The Windows NT Executive: The Underlying, "New Technology"
microkernel-based operating system that supports one or more protected subsystems. NT includes a number of kernel-mode components with well defined functionality isolated in each component. Those of most interest to NT device driver writers are the Kernel, I / O Manager, Hardware Abstraction Layer (HAL), Configuration Manager, Memory Manager, Executive Support, and Process Structure components. Additional components of interest to some NT driver writers include the Object Manager and Security Reference Monitor. Also of interest to NT file system driver writers is the Cache Manager. Like NT itself, NT drivers are implemented as discrete, modular components with a well defined set of required function- ality. All NT drivers have a set of system-defined standard driver routines and some number of internal routines as determined by the driver Writer. There are Three Basic Types of NT Drivers. Each Type Has A Slightly Different Structure and Quite Different FunctionAlity:
