Linux •
Linux is an open source operating system, is currently high market share of the server operating system. Currently it has many branches. Andrews
• Unix (understand)

2. Why use Linux operating system
Watch films online: http: //goto.red/ilU955
The reason why most of the time are developed using the Linux operating system, depends on two characteristics:
Stability: depends on the underlying system architecture, general Linux system can do for a long time does not shut down is not Caton ;
security: open source, anyone can contribute their source code patch for Linux systems;
3, Linux Introduction (understand)
3.1, Linux operating system
• character of Linus
Linux development author, Linus Torvalds. Dutch college students.
• 1991 Nian version 0.0.1
Linus was used in schools is the Unix operating system and its underlying code system was modified into a school open to students on the site, he originally wrote the file named Linus's Unix, network management after the late discovery that the name is not good, to manually change the name of the Linux. Then other students found that this version is still very good use after download, then put their code contributions to Linus.
• 1992 In 0.0.2 version
• 1994 Version 1.0
• 2003 2.6 version
mentioned above refers to the version of Linux kernel version, does not mean release branch.
3.2, the open source culture

• People Stallman Eastman

• 1991 Nian Stallman find Linus, adding that talks so that Linux open-source project (GNU Project)
• 1992 in GNU / Linux
3.3, Linux branch
Currently branches are more common with centos (community enterprise network operating system), RedHat, Ubuntu, debian and so on.
In particular branch, you can view the Linux bifurcation diagram [file] in.
