What is Windows NT architecture?
The Windows NT kernel is a hybrid kernel; the architecture comprises a simple kernel, hardware abstraction layer (HAL), drivers, and a range of services (collectively named Executive), which all exist in kernel mode. The kernel is also responsible for initializing device drivers at bootup.
What is the general structure of Windows NT operating system?
The architecture of Windows NT is highly modular, and consists of two main layers: a user mode and a kernel mode. Programs and subsystems in user mode are limited in terms of what system resources they have access to, while the kernel mode has unrestricted access to the system memory and external devices.
