Quick Answer: Is the Linux kernel monolithic?

Linux is a monolithic kernel while OS X (XNU) and Windows 7 use hybrid kernels. Let’s take a quick tour of the three categories so we can go into more detail later. A microkernel takes the approach of only managing what it has to: CPU, memory, and IPC.

Why Linux kernel is monolithic?

Monolithic kernel means that the whole operating system runs in kernel mode (i.e. highly privileged by the hardware). That is, no part of the OS runs in user mode (lower privilege). Only applications on top of the OS run in user mode. … In either case, the OS can be highly modular.

What is microkernel OS?

In computer science, a microkernel (often abbreviated as μ-kernel) is the near-minimum amount of software that can provide the mechanisms needed to implement an operating system (OS). These mechanisms include low-level address space management, thread management, and inter-process communication (IPC).
