Linux is the name for the kernel of an operating system that is based on the UNIX principles. The name is derived from the first name of its Finnish inventor, Linus Torvalds, and follows the methodology used by other UNIXbased systems (the last letter is an x). Today, Linux is developed and maintained by thousands of people around the world. The kernel of an operating system is its heart. It is required for communication between the hardware of your computer and you, the user. An operating system is a collection of different software components: a kernel, various tools and the accompanying libraries. It is a software that extends the basic operating system of your computer, known as the BIOS.
