What are the operating system architecture?
The kernel is the core of an operating system. It is the software responsible for running programs and providing secure access to the machine’s hardware. Since there are many programs, and resources are limited, the kernel also decides when and how long a program should run.
What do you mean by operating system explain architecture of operating system with diagram?
An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs. Other specialized classes of operating systems (special-purpose operating systems), such as embedded and real-time systems, exist for many applications.
What is layered architecture in operating system?
Layered Structure is a type of system structure in which the different services of the operating system are split into various layers, where each layer has a specific well-defined task to perform.

What is the architecture of an operating system?
3. A monolithic os is an operating system architecture where the entire operating system is working in kernel space and is alone in supervisor mode. Every component of the operating system is contained in the kernel and can directly communicate with any other (i.e., simply by using function calls).
What kind of architecture does Windows 2000 have?
