Linux operating system is probably the most well-known open-source OS in the world. It is a Unix-like OS, and the key feature of Linux is the Linux kernel. It was released in September 1991, and its creator is now famous Fin Linus Torvalds.
Originally envisioned to be a personal computer OS, now it runs on many platforms, much more than originally planned. Ever since Android came to be the dominant power in the mobile phone world, Linux became the OS with the largest installed base. What is even more impressive is that Linux runs 99.6% of the TOP500 supercomputers. Linux also runs 2.3% of all desktops and also is most prominent in the embedded systems market, running TiVo, network routers, TV’s, video game consoles, smartwatches and much more.
The predecessor of Linux, Unix OS, was implemented more than 45 years ago in the US, by AT&T engineers. Unix later evolved into many alterations, and Linus Torvalds stated himself that if one of those versions – the GNU kernel had been available at the time, he would not have started developing Linux. Luckily, he decided to go on with the work, and this is how Linux was born.
Torvalds was most frustrated with the fact that MINIX was only one of the many operating systems which needed licensing. He started to develop his kernel which eventually came to be Linux kernel. At first, he wanted to name the new OS “Freax,” but gave on the idea when one of his coworkers dismissed it. Hence, Linux was born. Today, Linux is present everywhere in the computer world, from embedded systems to supercomputers, its greatest success probably being the smartphone market. Currently, Linus still leads the team of software engineers working on all the upgrades and developments of Linux.
