History of Unix Operating System
The Unix operating system has taken thirty years to evolve into present scenario. Here are some key events which led to its development.
Within 1971 the first edition of the Unix server operating system emerged from Bell Labs. While Linux does not involve any Unix code, this is a Unix clone, that means it shares a number of technical characteristics with Unix, that may be considered the forerunner of the open-source operating system. In During the 1970s, Unix code was distributed to people at several universities and industries, and they created their own Unix varieties, that ultimately evolved into Sun Microsystems', Berkeley's FreeBSD Silicon Graphics' and Solaris IRIX.
Within 1985 Richard Stallman published his famed "GNU Manifesto", one of the first documents of the open- source revolution. A Stallman began working on the GNU operating system in the year of 1983, hugely since he wanted to create an open-source version of Unix. (GNU is stands for "GNU is Not Unix.") A Stallman's Free Software Foundation later created the GNU General Public License, the largely adopted and fully legal "anticopyright" treatise in which today pemits Linux and other software to remain completely free.
In the year of 1987 invented Minix by the Professor Andrew S. Tanenbaum, an open-source operating system that is a clone of Unix. A Young Linus Torvalds, at present a computer science student in Finland which was introduced to Minix and based his plans for Linux on the Minix example.
In August 1991 year, Torvalds announced his plans to establish a free operating system on the Minix user's newsgroup. He modestly noted in his posting which his OS is just a hobby. It would not be professional and big like GNU. In the October, Linux 0.01 was released on the Internet under a GNU public license. Within the Minix newsgroup, Torvalds asks his fellow programmers to lend a hand in making the system more workable. He gets sufficient help to release version 0.1 through December. Over the next various years, the number of Linux developers swelled into the hundreds of thousands and worked to make Linux compatible with GNU programs. The Vendors such as Red Hat, Debian and Caldera created popular distributions of Linux which bundled the operating system with useful programs and a graphical interface.
In the year of 1997 Torvalds moved to Silicon Valley and went to work at Transmeta.
In August year of 1999, Red Hat finished its initial public offering, making it the first Linux-oriented industries to successfully go public. In the December month, Andover.net, a consortium of Web site resources hugely devoted to Linux and VA Linux, a producer of Linux hardware, had wildly successful IPOs. The Linuxcare, a leading Linux service provider, announces alliances with like company giants as Dell, IBM, Informix and Motorola.
