Unix (/ ˈ j uː n ɪ k s / ⓘ, YOO-niks; trademarked as UNIX) is a family of multitasking, multi-user computer operating systems that derive from the original AT&T Unix, whose development started in 1969 [1] at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others.
3BSD (1979) UNIX System III (1981) UNIX/V7M (1979) UNIX Time-Sharing System v8 (1985) UNIX Time-Sharing System v9 (1986) UNIX Time-Sharing System v10 (1989) IX Multilevel-Secure UNIX System (1992) The versions leading to v7 are also sometimes called Ancient UNIX. After the release of Version 10, the Unix research team at Bell Labs turned its ...
For the first time in 1970, the Unix operating system was officially named and ran on the PDP-11. A text-formatting program called roff and a text editor were added. All three were written in PDP-11 assembly language. Bell Labs used this initial text-processing system, consisting of Unix, roff, and the editor, for text processing of patent ...

Unix architecture. A Unix architecture is a computer operating system system architecture that embodies the Unix philosophy. It may adhere to standards such as the Single UNIX Specification (SUS) or similar POSIX IEEE standard. No single published standard describes all Unix architecture computer operating systems — this is in part a legacy ...
Preemptive multitasking was implemented in the PDP-6 Monitor and Multics in 1964, in OS/360 MFT in 1967, and in Unix in 1969, and was available in some operating systems for computers as small as DEC's PDP-8; it is a core feature of all Unix-like operating systems, such as Linux, Solaris and BSD with its derivatives, [7] as well as modern ...
