The kernel lockdown limits the root (UID 0) account access to kernel features that enable arbitrary code modification and execution. This way, the Linux kernel remains safe even when the root account is compromised. Linux kernel lockdown comes in two modes- Integrity and Confidentiality. ...
The kernel is termed as the heart of any operating system as it controls all other programs in a system. When a device starts, the kernel goes through a process called the initialization function, such as checking memory. It takes care of the memory allocation part and creates an environment...
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 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 is a monolithic kernel that's constantly growing; it had 20 million lines of code in 2018. From a foundational level, it's layered into a variety of subsystems. These main groups include a system call interface, process management, network stack, memory management, virtual ...

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. ...
Linux kernelUpdated: 12/20/2024 by Computer HopeThe Linux kernel is the foundation of any Linux-based operating system. It represents the core of Linux distributions for servers and desktop computers. It's also used in embedded systems, such as routers, and in all Android-based systems, ...
Linus never shipped an “embedded version” of the Linux kernel. As an embedded developer, you may not require a tailored kernel for your system and might rely on an official release instead. However, it is often the case that you may need a kernel configured to support your custom hardware...
Kernel-Version: Docker requires a Linux kernel version of 3.10 or higher. You can check your kernel version by running the command: uname -r CPU: Docker typically works well with modern CPUs. However, virtualization extensions (e.g., Intel VT-x or AMD-V) need to be enabled in the BIOS...
