History of linux
Linux operating system is similar to Unix. The Linux kernel was made open to the public on 17th September 1991. This was done for the Intel x86 PC architecture. When system utilities and libraries were added from the GNU project, an alternate system GNU/Linux was created. Linux is separated by corporations like Dell, Hewlett-Packard, Novell, IBM, Red Hat, Oracle Corporation and Sun Microsystems. These operating systems are used for desktop computers, supercomputers, video game systems, arcade games, mobile phones and routers.
Development
The Unix operating system was developed in the 1960s and released in 1970. It was widely used by academic institutions and businesses. The design influenced authors of other systems. One system similar to Unix was GNU. This was started in 1984. The aim was to create a total Unix-compatible software system of free software. To spread the software freely, Richard Stallman created the Free Software Foundation. The GNU General Public License was also developed. Most of the programs needed in an operating system were done in the early 1990s. These were compilers, libraries, a Unix shell, text editors and a windowing system. Low level elements like daemons, device drivers and the kernel were not completed.
MINIX
MINIX is also similar to Unix operating system. This was released in 1987 by Andrew S. Tanenbaum. This system was developed for academic use. The source code of the system was not allowed to be modified or redistributed. MINIX’s 16-bit design was not in conformance with the 32-bit design of the Intel 386 architecture of personal computers. This architecture was very inexpensive and famous. Linus Torvalds attended the University of Helsinki in 1991. There he worked on a non-commercial substitute for MINIX. At the end, this replacement was called as the Linux kernel. Linux had to depend on the MINIX userspace. Code from the GNU system could be easily used. The code given a licence under the GNU GPL could be used in other projects as long as they were released under the same or compatible licence. To have compatibility between the Linux kernel and the GNU project, Torvalds started a switch from the basic licence. Linux and GNU developers collaborated to combine the GNU components with the Linux operating system so that a free and completely functional operating system forms.
Use
Linux can be used in embedded systems or in supercomputers. As it has a popular LAMP application stack, it has a place in server installations. Torvalds had a major role in the development of the kernel. Stallman is the head of the Free Software Foundation and this is supportive of the GNU components. Lastly, individuals and corporations create third party non-GNU components. These components include a large body of work. They may have kernel modules, user applications and libraries. Linux vendors and communities mix as well as distribute the kernel, GNU components and non-GNU components.
Linux distribution
A linux distribution is also called as a distribution or distro. This is a member of the Linux family of computer operating systems similar to Unix. These systems are developed from the Linux kernel and other packages like the XWindow system and software from the GNU project.
