Linux and UNIX both are operating systems written in C and Assembly languages. UNIX is a primary operating system introduced in the year 1970 by Ken Thompson and others, while it is a multitasking and multiuser operating system. UNIX being a proprietary networking OS, its cost is high for a mainframe system. The end-users of UNIX are not authorised to change the kernel in any way as it results in the violation of the licence in the terms. Later in the year 1991, a Finnish student named Linus Torvalds introduced the initial Linux kernel, which meant a clone of the UNIX. Linux is an open-source operating system and free for anyone to use and modify the code. Nowadays Linux OS is widely used in day to day life like Supercomputers, desktops, smartphones, web server, home appliances, washing machines, refrigerators, cars, modems etc.

Operating system: Each time when we turn on your computer, we can see and perform different activities on the system like write, read, browse the internet and watching a video. Well, all these activities are performed by an operating system or kernel. A kernel is a program which is the heart of any operating system, used to communicate between hardware and software. So, to work on the computer we need an operating system. Nowadays Linux is in great demand and popularly used in everywhere. Linux is an open-source operating system which is freely downloaded and distributed over the internet. With time, Linux became an important backbone for an operating system like Knoppix, Debian, Ubuntu, and Fedora etc.
