System calls provide the interface between a process and the operating system. Most operations interacting with the system require permissions not available to a user-level process, e.g.,
A kernel is a component of a computer operating system. [1] A comparison of system kernels can provide insight into the design and architectural choices made by the developers of particular operating systems.
A monolithic kernel is an operating system architecture with the entire operating system running in kernel space. The monolithic model differs from other architectures such as the microkernel [1] [2] in that it alone defines a high-level virtual interface over computer hardware. A set of primitives or system calls implement all operating system ...

The architecture of Windows NT, a line of operating systems produced and sold by Microsoft, is a layered design that consists of two main components, user mode and kernel mode.

MinWin is a term used informally by Microsoft to describe the kernel and operating system components that form the basis of releases of Microsoft Windows starting with Windows Vista. The term was first used in 2003 to describe approximately 95% of the common components of the operating system, but has over time come to refer to a significantly ...
