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 ...
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.
The Linux kernel is both monolithic and modular, since it can insert and remove loadable kernel modules at runtime. This central component of a computer system is responsible for executing programs. The kernel takes responsibility for deciding at any time which of the many running programs should be allocated to the processor or processors.
The fact that Linux is a monolithic kernel rather than a microkernel was the topic of a debate between Andrew S. Tanenbaum, the creator of MINIX, and Torvalds. [24] The Tanenbaum–Torvalds debate started in 1992 on the Usenet group comp.os.minix as a general discussion about kernel architectures. [25] [26]
Multiserver Microkernel (Hurd kernel) or Monolithic (Linux-libre kernel, fork of Linux kernel, and other kernels which are not part of the GNU Project) C: 1:1 Unix-like: 2.4 on Linux-libre kernel (not on Hurd kernel) Linux: ReactOS: GPL, LGPL Hybrid C, C++ Windows-like: No RISC OS: Apache 2.0 Monolithic (with cooperative multitasking) ARM ...
Unix systems use a centralized operating system kernel which manages system and process activities. All non-kernel software is organized into separate, kernel-managed processes. Unix systems are preemptively multitasking : multiple processes can run at the same time, or within small time slices and nearly at the same time, and any process can ...
The Tanenbaum–Torvalds debate was a written debate over the Internet between Andrew S. Tanenbaum and Linus Torvalds, regarding the Linux kernel and kernel architecture in general. Tanenbaum, the creator of Minix , began the debate in 1992 on the Usenet discussion group comp.os.minix , arguing that microkernels are superior to monolithic ...
This article documents the version history of the Linux kernel. Each major version – identified by the first two numbers of a release version – is designated one of the following levels of support: Supported until next stable version; Long-term support (LTS); maintained for a few years [1]
