Key Concepts & Definitions

Linux Kernel
The core component of the Linux operating system responsible for managing hardware, system resources, and providing essential services to software. It acts as an intermediary between hardware and user applications, ensuring efficient and secure operation.

Kernel Version
A specific release of the Linux Kernel identified by a version number (e.g., 5.15.0). It indicates the particular set of features, fixes, and improvements incorporated into that release, and is used to ensure compatibility with hardware and software.

Kernel Architecture
The structural design of the Linux Kernel, which can be monolithic, microkernel, or hybrid. It defines how the kernel is organized, how it manages system components, and how it interacts with hardware and software layers.

Kernel Responsibilities
The fundamental tasks performed by the Linux Kernel, including process management, memory management, device control, system calls handling, and security enforcement. These responsibilities ensure the stability and efficiency of the operating system.
