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. The most recent version of Linux for personal computers is 5.6 (kernel).
2. FreeBSD :
FreeBSD is a free and open source operating system which is provided The FreeBSD Project. It was designed on the basis of the two Unix-like operating systems Berkeley Software Distribution (BSD) and Research Unix. It has quite similarities with Linux operating system. It was one of the famous operating systems earlier but now it is less used as compared to other operating systems. The first version of FreeBSD was launched in 1993. The latest stable version of FreeBSD is 12.1.
