UNIX Development History

(1) In 1965, the United States Massachusetts Institute of Technology (MIT), GE (FE) and T Bell Labs jointly developed the Multics project, with the goal of developing an interactive time-sharing operating system with multi-channel process capabilities, But because the goal of Multics is too large and complex, the project is far behind the plan, and finally Bell Labs announced its exit.

(2) In 1969, the Ken Thompson of Bell Labs in the United States developed a UNIX system on the DEC PDP-7 machine. (3) In 1971, Ken Thompson's colleague Dennis Ritchie invented the C language; In 1973, most of the UNIX system's source code was rewritten in C, which lays the groundwork for improving the portability of UNIX systems.   Unix Major releasesOperating system             company               &N       Bsp   Hardware platform    aix                  IBM         & nbsp             powerpc   hp-ux               &N HP Bsp                      pa-riscsolaris         &NB Sp   Sun                        SPARCLINUX,BSD         Red Hat Linux,        ia (intel,amd,              &NB Sp         UBUNTU,FREEBSD          cyrix,rise ...         linux System Introduction Linux system was born in 1991 by Finnish University students Linus (Linus Torvalds) and subsequently joined the many enthusiasts to complete.         &NBSP  linux is free software, is the source code open unix.           Linux Major ReleasesFree Software Free SoftwareFreedom of use can be free from any restrictions on the use of software research freedom can obtain software source code, research software operation mode of freedom can freely copy software and spread to others to improve the freedom can be self-improvement software and spread the modified version Linux System Architecture X Window IntroductionX Window System features: independent of operating system source code free network features UNIX graphics environment: CDE (General desktop environment) (commin desktop environment) CDE Linux Application AreasE-commerce network applied Science computing embedded applications .....

Turn, there are some borrowed micro Bo (lamp brother Lian _ Powerful) Figwinlif and other friends article. Thanks Brother Lian _ Strong, Figwinlif.
