Linux ( Legend Of Operating Systems )

 Linux is a family of open-source Unix-like operating systems based on Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged in a Linux distribution. 

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name "GNU/Linux" to emphasize the importance of GNU software, causing some controversy.

Some Versions Of Linux Operating System

Ubuntu

Ubuntu is a Linux distribution based on Debian and composed mostly of free and open-source software.

Arch Linux

Arch Linux is a Linux distribution for computers with x86-64 processors. Arch Linux adheres to the KISS principle and is focused on simplicity, modernity, pragmatism, user centrality, and versatility. In practice, this means the project attempts to have minimal distribution-specific changes, and therefore minimal breakage with updates, and be pragmatic over ideological design choices and focus on customizability rather than user-friendliness.

CentOS Linux

The CentOS Linux distribution is a stable, predictable, manageable and reproducible platform derived from the sources of Red Hat Enterprise Linux (RHEL). We are now looking to expand on that by creating the resources needed by other communities to come together and be able to build on the CentOS Linux platform. And today we start the process by delivering a clear governance model, increased transparency and access. In the coming weeks we aim to publish our own roadmap that includes variants of the core CentOS Linux.

• Developer: The CentOS Project, (affiliated with Red Hat)
• OS family: Linux
• Working state: Current
• Source model: Open source
• Marketing target: Servers · desktop computers · workstations · supercomputers
• Package manager: Yum (command line); PackageKit (graphical); .rpm (binaries format)

These were some versions of Linux Operating System.
