Linus Torvalds year (1991). Version 1.0 was released on March 14, 1994. Torvalds first encountered the GNU Project in 1991, after another Swedish-speaking computer science student, Lars Wirzenius, took him to the University of Technology to listen to free software-guru Richard Stallman's speech. Torvalds used Stallman's GNU General Public License version 2 (GPLv2) for his Linux kernel. After a visit to Transmeta in late 1996, Torvalds accepted a position at the company in California, where he would work from February 1997 until June 2003. He then moved to the Open Source Development Labs, which has since merged with the Free Standards Group
Operating system Digital Equipment Corporation developed many operating systems for its various computer lines, including TOPS-10 and TOPS-20 time sharing systems for the 36-bit PDP-10 class systems. Before the widespread use of UNIX, TOPS-10 was a particularly popular system in universities, and in the early ARPANET community. RT-11 was a single-user real-time OS for the PDP-11 class minicomputer, and RSX-11 was the corresponding multi-user OS. From the late 1960s through the late 1970s, several hardware capabilities evolved that allowed similar or ported software to run on more than one system. Early systems had utilized microprogramming to implement features on their systems in
