Linux was originally developed as a free operating system for personal computers based on the Intel x86 architecture, but has since been ported to more platforms than any other operating system because of the dominance of Android on smartphones, Linux has the largest installed base of all general-purpose operating systems. Linux. It’s been around since the mid ‘90s, and has since reached a user-base that spans industries and continents. For those in the know, you understand that Linux is actually everywhere. It’s in your phones, in your cars, in your refrigerators, your Roku devices. It runs most of the Internet, the supercomputers making scientific breakthroughs, and the world\'s stock exchanges. But before Linux became the platform to run desktops, servers, and embedded systems across the globe, it was (and still is) one of the most reliable, secure, and worry-free operating systems available.
