History of linux

Linux is a modular Unix-like operating system. Linux has a lot of design that comes from the basic design of Unix that was developed in the period of the 1970s and 1980s. Its wide availability and portability meant that Unix can be used, copied and modified extensively by academic institutions and the business. But one thing is very unfortunate at this time is that we can not arbitrarily modify Unix and freely disseminate to the publicgeneral. The GNU Project, started in 1984 has the aim to create an operating system that is compatible with Unix and totally complete and consists of free software. In 1985, Richard Stallman founded the Free Software Foundation and developed the GNU General Public License (GNU General Public License or GNU GPL). Most programs required by an operating system (such as libraries, compilers, text editors, a Unix shell and window system) were completed in the early 1990s, but unfortunately the low-level elements such as device drivers, daemon andkernel is still not finished, that's when (1991) Linus Torvalds announced that it has made a kernel that is based on Unix, called Linux, it is certainly no coincidence that at the time the project requires GNU kernel (the kernel does not have), it can be seen of statements that Linus Torvalds has said that if the GNU kernel had been available at that time (1991), he would not have decided to write his own.The Maestro is understated :

Linux itself was inspired by Minix. MINIX, a Unix-like system intended for academic use released by Andrew S. Tanenbaum in 1987. MINIX 1.0 source code contained in his book Operating Systems: Design and Implementation. Although it can be easily obtained, modification and redistribution is not allowed at the time. The copyright of the source code is included in the copyright of the book, published by Prentice Hall. In addition, the design of the 16-bit versions of MINIX then not well adapted to the 32-bit version ofIntel 386 architecture is cheap and popular widely used in personal computers. In 1991, Torvalds began work to create a non-commercial version of the replacement MINIXsewaktu he studied at the University of Helsinki. The results of his work that would later become the Linux kernel. Linux itself is like its own version of Unix, whose creation and development does not have a relationship with Minix, It can be seen in 1992, where Tanembaum wrote an article on Usenet, claiming that Linux is outdated. In his article, he criticized Linux asan operating system with a monolithic design and too fixated with the x86 architecture that is not portable, in which he described as a "fundamental mistake". Tanenbaum suggests that those who want a modern operating system should look for a design that is based on the microkernel model. The article emphasizes the responsibility Torvalds lead to a debate about the design of a monolithic kernel and microkernel. (Minix kernel has a microkernel types possess temporal Linux Kernel type Monolitic).Today Linux has been used in various domains, from embedded systems tosupercomputers, and has had a safe position in the installation of LAMP application webserver with her popular. Linux kernel development was continued olehTorvalds, while Stallman heads the Free Software Foundation, which supports the development of GNU components. In addition, many individuals and companies who develop non-GNU components. Linux communities combine and distribute the kernel, GNU components, and non-GNU software package management in Linux distributions.
