The Linux kernel is a free and open source, [11]: 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 distributions that have highly modified kernels — for example, real-time computing kernels — should be listed separately. There are also a wide variety of minor BSD operating systems, many of which can be found at comparison of BSD operating systems .
In computing, unique set size (USS) is the portion of main memory occupied by a process which is guaranteed to be private to that process. The unshared memory of a process is reported as USS. [1] This concept is used for software running under the Linux operating system. [2]
This article documents the version history of the Linux kernel.. Each major version – identified by the first two numbers of a release version – is designated one of the following levels of support:
Tiny Core Linux is an example of Linux distribution that run from RAM. This is a list of Linux distributions that can be run entirely from a computer's RAM, meaning that once the OS has been loaded to the RAM, the media it was loaded from can be completely removed, and the distribution will run the PC through the RAM only.
RTLinux is a hard realtime real-time operating system (RTOS) microkernel that runs the entire Linux operating system as a fully preemptive process. The hard real-time property makes it possible to control robots, data acquisition systems, manufacturing plants, and other time-sensitive instruments and machines from RTLinux applications.
Gentoo describes itself as a meta-distribution because of its adaptability, in that the majority of its users have configurations and sets of installed programs which are unique to the system and the applications they use. [5] Gentoo Linux is named after the gentoo penguin, the fastest swimming species of penguin. The name was chosen to reflect ...
The Linux 2.4 ports were forward ported from the 2.0.36 Linux kernel by Michael Leslie and Evan Stawnyczy during their work at Rt-Control. There were never any μClinux extensions applied to the 2.2 series kernels. Since version 2.5.46 of the Linux kernel, the major parts of μClinux have been integrated with the mainline kernel for a number of ...
