What is Linux?
Linux is a free, open-source operating system.
The root of every Linux system (every distribution) is the kernel, initially developed by Linus Torvalds. In addition to being free to use and redistribute, Linux supports virtually all platforms, including PCs and Macs.
At its core, Linux is based on the Unix operating system and Unix-like operating systems such as System V, BSD, and GNU/Linux.
The term “Unix” is a registered trademark of The Open Group, and is commonly used to refer to the large set of operating systems that resemble the original Unix. As mentioned, Unix operating systems run successfully on various computer architectures, both as servers and workstations. Particularly noteworthy is the fact that operating systems such as Android and iOS, found on all popular smartphones, are based on Unix and Linux — which speaks for itself in terms of the widespread adoption, quality and future of this type of operating system.
