What is the architecture of operating system?
A monolithic kernel is an operating system architecture where the entire operating system is working in kernel space. The monolithic model differs from other operating system architectures, such as the microkernel architecture, in that it alone defines a high-level virtual interface over computer hardware.
What are the 5 desktop operating systems?

Why do we need software architecture?
Software architecture represents a common abstraction of a system that most if not all of the system’s stakeholders can use as a basis for mutual understanding, negotiation, consensus, and communication. It is also the earliest point at which design decisions governing the system to be built can be analyzed.
What is the use of software architecture?
Architecture serves as a blueprint for a system. It provides an abstraction to manage the system complexity and establish a communication and coordination mechanism among components.
What is the architecture of Windows operating system?
Kernel mode in Windows NT has full access to the hardware and system resources of the computer.
