A key part of kernel operation is communication with hardware devices inside and outside of the physical computer. However, it isn't practical for an OS to interact with every possible device in existence. Instead, kernels rely on the ability of device drivers, which add kernel support to spe...
The Linux kernel is currently distributed under GNU's General Public License.The Linux kernel is a "monolithic" architecture— the OS (Operating System) operates entirely in the kernel space. In contrast, in a microkernel architecture, the kernel alone defines and controls how the operating system...
While they all have the Linux kernel in common, various Linux distributions build their own operating systems on top of the basic open-source foundation. Linux distributions, referred to as “distros,” boast a range of backgrounds and features. Ubuntu is the world’s most popular free OS and...
What Is a Linux Kernel? The Linux kernel is central to the Linux computer operating system. The kernel is the core interface between a computer's hardware and its processes, making sure there is available memory for Linux applications to run, optimizing processors, and navigating system requiremen...
Linux kernel vs. Linux operating system A kernel is a computer program that functions as the beating heart of the OS, the system that allows users to interact with the computer’s hardware and software. In the case of the Linux OS, the Linux kernel is the code that forms the core compon...

The /proc/vmcore file is thus one of the most common sources for kernel core dumps. The data is represented in ELF (Executable and Linkable Format), which we will discuss a bit more later on. However, if you were to go searching on your Linux machine for a /proc/vmcore file, you pr...
What is a kernel panic? A kernel panic is one of several Linux boot issues. In basic terms, it is a situation when the kernel can't load properly and therefore the system fails to boot. During the boot process, the kernel doesn't load directly. Instead,initramfsloads in RAM, then it...

system or, in the case of Linux, by introducing a newer kernel or modifying an existing kernel. Windows and macOS, like Linux, have their own kernels that are all distinct. The Linux kernel is the main common component among the different Linux distributions available, whether broad or ...
