What are the different types of operating system architectures?

There are several types of operating system architectures, including monolithic, microkernel, and hybrid architectures. Would you like to know more about each?

Yes, please explain the monolithic architecture.

In a monolithic architecture, the entire operating system runs as a single program in kernel mode. This means that all services, like device drivers and file management, are part of the kernel, which can lead to better performance but less modularity.

What about microkernel architecture?

Microkernel architecture minimizes the core functions of the OS, running most services in user space. This enhances modularity and stability, as faults in user services do not crash the kernel.

Can you give an example of a hybrid architecture?

Sure! A hybrid architecture combines elements of both monolithic and microkernel designs. Windows NT is a well-known example, where it uses a microkernel for core functions but allows some services to run in kernel mode for performance.
