Return to Linux, Linux topics or Kernel
TLDR: The Linux Kernel is the core component of the Linux operating system, initially released by Linus Torvalds in 1991. It is a Linux monolithic kernel that manages Linux hardware resources, Linux system processes, and Linux security for Linux-based distributions. Known for its Linux kernel stability, Linux kernel scalability, and Linux open-source nature, the Linux Kernel powers a wide range of Linux devices, from desktops and servers to embedded systems and mobile devices.

The Linux Kernel facilitates communication between hardware and software by handling critical functions such as Linux kernel memory management, Linux kernel process scheduling, and Linux kernel device control. It supports a wide variety of file systems, including EXT4, Btrfs, and XFS, ensuring Linux kernel compatibility with a wide variety of Linux use cases. Linux kernel regular updates introduce new Linux kernel features, improve Linux kernel hardware support, and enhance Linux kernel security, making it a dynamic foundation for modern computing.
As the backbone of Linux cloud computing, Linux supercomputing, and Linux IoT, the Linux Kernel supports Linux technologies like KVM (Kernel-based Virtual Machine), Docker, and Kubernetes. Its Linux kernel modular design allows for Linux kernel customization, enabling Linux kernel developers to tailor the kernel for specific Linux environments. By fostering a Linux global community of Linux kernel contributors, the Linux Kernel continues to evolve, driving Linux innovation and maintaining its position as a cornerstone of the Linux open-source Linux ecosystem.
The Linux kernel is a free and open source,: 4 Unix-like kernel that is used in many computer systems worldwide. The kernel was created by Linus Torvalds in 1991 and was soon adopted as the kernel for the GNU operating system (OS) which was created to be a free replacement for Unix. Since the late 1990s, it has been included in many operating system distributions, many of which are called Linux. One such Linux kernel operating system is Android which is used in many mobile and embedded devices.
Most of the kernel code is written in C as supported by the GNU compiler collection (GCC) which has extensions beyond standard C.: 18 The code also contains assembly code for architecture-specific logic such as optimizing memory use and task execution.: 379–380 The kernel has a modular design such that modules can be integrated as software components – including dynamically loaded. The kernel is monolithic in an architectural sense since the entire OS kernel runs in kernel space.
