The history of Unix dates back to the mid-1960s, when the Massachusetts Institute of Technology, AT&T Bell Labs, and General Electric were jointly developing an experimental time-sharing operating system called Multics for the GE-645 mainframe. [1] Multics introduced many innovations, but also had many problems.
UNIX is a computer operating system. It was first developed in 1969 at Bell Labs. Ken Thompson, Dennis Ritchie, Douglas McIlroy, and others created it. They used assembly language to write it. In 1972, the Unix code was rewritten with the new C programming language.
Linux ( / ˈlɪnʊks / LIN-uuks) [11] is a family of open-source Unix-like operating systems based on the Linux kernel, [12] an operating system kernel first released on September 17, 1991, by Linus Torvalds.
