Unix
Unix
Unix (/ˈjuːnɪks/; trademarked as UNIX) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, development starting in the 1970s at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others.
Etymology
The name "Unix" (pronounced /ˈjuːnɪks/) is a portmanteau of "Uniplexed Information and Computing Service," a reference to the fact that the operating system was originally developed for a single-user, single-tasking environment.
