Unix是对所有硬件供应商运营的所有繁琐手续的一大变革。相比之下，Unix是由少数人开发的。1969夏季UNIX在贝尔电话实验室原名是新闻了。肯·汤普森是引发Dennis Ritchie和陆克文该是活跃的贡献者。主要目的是为他们营造一个舒适的环境。与其他竞争对手相比，Unix是易于使用和理解的。使UNIX如此流行的最重要的因素是源代码，它在开始时是免费的。后来，AT&T意识到他们在Unix中有一些伟大的价值观，并试图利用这一点，大学被禁止使用教育中的源代码。这促使Andy Tananbaum写Minix，从Linus Torvalds那里得到灵感为他的英特尔386写一个内核，内核，后来成为莱纳斯Torvalds的Linux，一个赫尔辛基大学的学生买了一台电脑和一个英特尔80386处理器，4 MB的内存和40 MB的硬盘驱动器-古怪的在今天的计算环境，但相当强大的个人设置为1991。这也与微软个人计算机的DOS（磁盘操作系统）作为其标准的软件但是Torvalds根本没有兴趣，DOS。他一直喜欢他在学校学习的UNIX操作系统的技术方法。Torvalds来了解Minix是1990这是写作为教学工具由塔嫩鲍姆教授在阿姆斯特丹自由大学的一个简化的UNIX操作系统的克隆。MINIX开始所有的个人计算机和它的代码运行在低于100美元的可用软磁盘上。Torvalds安装这个代码他的电脑和开始建立自己的类UNIX操作系统内核，使用minix的脚手架。1991秋季Torvalds放手minix的支架和发布源代码为自己的新操作系统的内核，他称之为Linux。1994第一次正式的Linux版本1发布由Torvalds。Linux在十年末期成为了一个主要的技术和市场现象。1999，Linux成了一种公共关系现象。（Weber，2004）

UNIX came as a big change against all those burdensome propriety operating shipped by various hardware vendors. In contrast UNIX was developed by a small number of people. In summer 1969 UNIX was developed at Bell Telephone Laboratory whose original name was UNICS. Ken Thompson was the initiator and Dennis Ritchie and Rudd Canaday were active contributors. The main purpose was to create a pleasant environment for them. UNIX turned out to be easy to use and understand when compared to other competitors. The most important factor that made UNIX such a popular was the source code which was free in beginning. Later when AT&T realised that they had in UNIX of some great values and tried to capitalize on that, universities were forbidden to use the source code in education. This motivated Andy Tananbaum to write MINIX, from where Linus Torvalds got his inspiration to write a Kernel for his Intel 386, the Kernel that later became Linux.Linus Torvalds a student of university of Helsinki bought a personal computer with an Intel 80386 processor, 4 megabytes of memory, and a 40 megabytes hard drive - quaint in today's computing environment, but quite a powerful personal setup for 1991. This personal computer also came with Microsoft DOS (disk operating system) as its standard software but Torvalds was not at all interested in DOS. He always liked the technical approach of UNIX operating system which he was learning in his school. Torvalds came to know about Minix which is a simplified Unix clone in 1990 which was written as teaching tool by Professor Tanenbaum at Vrije University in Amsterdam. Minix started running on all personal computers and its code was available for less than $100 on floopy disks. Torvalds installed this code on his PC and started building the kernel of his own Unix like operating system, using Minix as the scaffolding. Torvalds in autumn 1991 let go of the Minix scaffold and released the source code for the kernel of his new operating system, which he called Linux. In 1994 the first official linux, version 1.0 was released by Torvalds. Linux became a major technological and market phenomenon at the end of the decade. And in 1999 Linux became a public relations phenomenon. (Weber, 2004)
