Linux is a “Unix-like” OS. It’s a clone of Unix but not based on it. At first, it was built only for Intel x86 architecture. However, now it has been ported to nearly all the architecture in existence.
Also, it has the largest user base within general operating systems and is the top mobile operating system with Android. And despite having only a 4% desktop share, approximately 96.4% of servers are run on Linux.
