Important differences between distributions of Linux lie in where they can be used, how they are supported, how they manage software updates, and what additional or optional components they include. How and where you can use various Linux distributions Some distributions include additional options such as a high-performance Linux kernel, management tools, a hypervisor, or even components for a cloud native environment. Generally, a Linux distribution includes core components including a bootloader, a Linux kernel, an init system, daemons, a graphical server, and applications.
System calls and security: Receive requests for service from the application processes.Ī Linux distribution (sometimes abbreviated as “Linux distro”) is a collection of key and optional components that combine to form a complete operating system.Device drivers: Act as an intermediary between the hardware and applications/processes.Process management: Determine which processes can use the central processing unit (CPU) and how.Memory management: Keep track of how much memory to leverage and how.The Linux kernel focuses on these critical functions: The kernel, existing inside a hard OS shell, controls all primary functions of the respective hardware, independent of the device, including mobile, tablet, desktop or laptop, server, etc. 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 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 requirements across applications. The Linux kernel is central to the Linux computer operating system.
