  1. 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 internal" API.

    Linux kernel. The Linux kernel is a free and open-source, [12] : 4 monolithic, modular, multitasking, Unix-like operating system kernel. It was originally written in 1991 by Linus Torvalds for his i386 -based PC, and it was soon adopted as the kernel for the GNU operating system, which was written to be a free (libre) replacement for Unix .

  4. The kernel's interface is a low-level abstraction layer. When a process requests a service from the kernel, it must invoke a system call, usually through a wrapper function . There are different kernel architecture designs. Monolithic kernels run entirely in a single address space with the CPU executing in supervisor mode, mainly for speed.

  5. The Linux kernel is a free and open-source, monolithic, Unix-like operating system kernel. It was conceived and created in 1991 by Linus Torvalds. [1] Linux kernels have different support levels depending on the version. Usually, each stable version continues to backport bug fixes from the mainline until the next stable version is released.

  6. The Linux Programming Interface is a well-regarded [3] work on Linux systems programming and is available for readers in several languages. [4] The Linux kernel API to userspace discussed in the book consists of both the System Call Interface and the GNU C Library.
