Pronounced “ewe-niks.” A multi-user, multitasking operating system originally developed by Ken Thompson and Dennis Ritchie at AT&T Bell Laboratories in 1969 for use on minicomputers. UNIX exists in various forms and implementations; among these are versions released by AT&T, the most recent being AT&T System V. UNIX is considered a powerful operating system that, because it is written in the C language, is more portable – that is, less machine – specific – than other operating systems. UNIX is available in several related forms, including ALX, a version of UNIX adapted by IBM (to fun on RISC-based workstations), A/UX (a graphical version for the Apple Macintosh), and Mach (a rewritten but essentially UNIX-compatible operating system for the Next computer).
