The Linux kernel is a free and open source, [12]: 4 Unix-like kernel that is used in many computer systems worldwide. The kernel was created by Linus Torvalds in 1991 and was soon adopted as the kernel for the GNU operating system (OS) which was created to be a free replacement for Unix.
Linux API, Linux ABI, and in-kernel APIs and ABIs. The Linux kernel provides multiple interfaces to user-space and kernel-mode code that are used for varying purposes and that have varying properties by design. There are two types of application programming interface (API) in the Linux kernel: the "kernel–user space" API; and; the "kernel ...
Linux: The Linux kernel is an operating system kernel used by the Linux family of Unix-like operating systems. GNU m4: GNU m4 is the GNU version of the m4 macro preprocessor. make: Make is a utility for automatically building executable programs and libraries from source code. Man-DB
Perl 5 gained widespread popularity in the late 1990s as a CGI scripting language for the Web, in part due to its parsing abilities. [15] Python is a widely used general-purpose, high-level, interpreted, programming language. [16] Python supports multiple programming paradigms, including object-oriented, imperative, functional and procedural ...
The Linux kernel is both monolithic and modular, since it can insert and remove loadable kernel modules at runtime. This central component of a computer system is responsible for executing programs. The kernel takes responsibility for deciding at any time which of the many running programs should be allocated to the processor or processors.
Zephyr uses Kconfig and devicetree as its configuration systems, inherited from the Linux kernel but implemented in the programming language Python for portability to non-Unix operating systems. [17] The RTOS build system is based on CMake, which allows Zephyr applications to be built on Linux, macOS, and Microsoft Windows. [18]
A kernel is a component of a computer operating system. [1] A comparison of system kernels can provide insight into the design and architectural choices made by the developers of particular operating systems.
