What is Linux OS?

Linux is an open source computing operating system. Its most notable feature is the Linux kernel, an operating system kernel. Linux was originally developed as a free operating system for personal computers based on the Intel x86 architecture, but has since been ported to several computer hardware platforms. It is the leading operating system on servers and other big iron systems such as mainframe computers and supercomputers. However it has limited adoption in personal desktop computers.

Linux also runs on embedded systems, devices whose operating system is typically built into the firmware and is highly tailored to the system. These include mobile phones, tablet computers, network routers, facility automation controls, televisions and video game consoles. Android, the leading smartphone OS is built on top of the Linux kernel and has the largest installed base of all general-purpose operating systems.
