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 component of the OS, enabling it to perform...
The Linux kernel communicates between the hardware and applications via "interrupts." When the hardware wants to interface with the application and broader system, an interrupt is issued across the processor and kernel to manage resources efficiently. The kernel, existing inside a hard OS shell, con...
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...
A Linux distribution (sometimes abbreviated as “Linux distro”) is a collection of key and optional components that combine to form a complete operating system. Generally, a Linux distribution includes core components including a bootloader, a Linux kernel, an init system, daemons, a graphical se...

Linux is an open-source operating system known for its security, reliability, and flexibility. Its core kernel manages hardware resources, process multitasking, and invites collaborative development under theGeneral Public License (GPL). There is a vast array of customizable Linux distributions and desk...
1) Linux Kernel Lockdown The principal feature addition on Linux kernel 5.4 is the kernel lockdown mode which aims to enhance Linux kernel security by separating the userland and kernel code. The kernel lockdown limits the root (UID 0) account access to kernel features that enable arbitrary ...
Linux is an open source operating system made up of the kernel, the base component of the OS, and the tools, applications, and services bundled with it.
首先接触到核（kernel）这个概念，还是早在学习离散数学的时候，同态的核。同态的核指的是同态映射中，映射到同态的象集中的单位元的原象的集合。（抱歉说得这么绕）当时就不懂为啥这玩意要叫核。凭啥它就叫核了呢？这个核有什么用呢？因为当时学得并不深入，所以这些疑问不了了之。后来这学期学了...
