Difference between Linux and NetBSD

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. NetBSD : NetBSD is a free and open source operating system which is provided by The NetBSD Foundation. It is based on the Berkeley Software Distribution. It is an Unix-like operating systems. It is available for many platforms including servers, desktops, handheld devices and embedded systems. The NetBSD project focuses on careful design, code clarity and portability across many computer architectures. The source code of NetBSD is publicly available and is permissively licensed. The first version of NetBSD was launched in 1993 and its kernel type is monolithic.
