Family of Unix-like operating systems This article is about the family of operating systems. For the kernel, see Linux kernel. For other uses, see Linux (disambiguation). Operating system Linux Tux the penguin, the mascot of Linux Developer Community contributors, Linus Torvalds Written ...
Their reasoning is that the operating system is seen as a modified version of the GNU operating system. Linux as a kernel is just a part of an operating system, whereas the whole operating system is basically the GNU system [6] [7] Several distributions of operating systems containing the Linux kernel use the name that the FSF prefers, such as ...
Linus Torvalds in 2002. In 1991, while studying computer science at University of Helsinki, Linus Torvalds began a project that later became the Linux kernel.He wrote the program specifically for the hardware he was using and independent of an operating system because he wanted to use the functions of his new PC with an 80386 processor.

Linux is not inherently fault-tolerant (no operating system is, as it is a function of the whole system including the hardware), but the flight computer software makes it so for its purpose. [68] For flexibility, commercial off-the-shelf parts and system-wide "radiation-tolerant" design are used instead of radiation hardened parts. [ 68 ]

The term GNU/Linux or GNU+Linux is used by the FSF and its supporters to refer to an operating system where the Linux kernel is distributed with a GNU system software. Such distributions are the primary installed base of GNU packages and programs and also of Linux. The most notable official use of this term for a distribution is Debian GNU/Linux.
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.
