1. Linux : Linux is a group of open source Unix-like operating systems which was developed by Linus Torvalds. It is a packaged of Linux distribution. Some of the mostly used Linux distribution are Debian, Fedora and Ubuntu. It was basically written in C language and assembly language. Kernel used in Linux is Monolithic kernel. The target systems of Linux distributions are cloud computing, embedded systems, mobile devices, personal computers, servers, mainframe computers and supercomputers. The first version of Linux was launched in 1991. 2. OS/2 : OS/2 is a series of operating system which was developed by co-ordination of Microsoft Incorporation and IBM. Its target systems are personal computers and servers. It is written using C, C++ and assembly language. The first version of OS/2 was launched in 1987. It was discontinued in 2006 and after that it was being updated, maintained and marketed under the name eComStation. In 2015 it was named ArcaOS. The kernel used in this operating system is Monolithic with modules.
