Linux is a clone of Unix, written from scratch by Linus Torvalds and released in 1991. Linux provides modern OS features, including true multitasking, virtual memory, shared libraries, demand loading, shared copy-on-write executables, proper memory management, and multistack networking including IPv4 and IPv6.
 
 
Although originally developed for 32-bit x86-based PCs (386 or higher), today Linux also runs on a multitude of other processor architectures, in both 32- and 64-bit variants.
 
Linux is one of the first and most successful community-driven, free and open-source software that has changed the way we build, distribute, and manage software. Linux is distributed under GNU/Linux license, which means any one can download, use, modify and distribute software.
 
Linux Kernel is the engine that runs all Linux based operating systems. Today, the Linux Kernel-based operating system powers billions of devices including servers, personal computers, embedded devices such as TV sets, wearables, automobiles, routers, gaming consoles, and smart appliances. Mobile devices, mainframes, and supercomputers run on Linux.
 
The most popular Linux Kernel-based operating systems are Ubuntu, Linux Mint, Debian, Fedona, RedHat/centOS and openSUSE.
The latest version of Linux kernel, Linux kernel 5.0, was just released. Some of the key features released in this version include AMD FreeSync display support, new console font for HiDPI/retina displays, Raspberry Pi Touchscreen support, Btrfs swap file support, Adiantum data encryption, and Logitech high-resolution scrolling.
