There are many different versions of UNIX. Until a few years ago, there were two main versions: the line of UNIX releases that started at AT&T (the latest is System V Release 4), and another line from the University of California at Berkeley (the latest version is BSD 4.4). Some other major commercial versions include SunOS, Solaris, SCO UNIX, AIX, HP/UX, and ULTRIX. The freely available versions include Linux and FreeBSD.
Many versions of UNIX, including System V Release 4, merge earlier AT&T releases with BSD features. The recent POSIX standard for UNIX-like operating systems defines a single interface to UNIX. Advanced features differ among systems.
Most versions of UNIX can also work with window systems, which allow each user to have more than one "terminal" on a single display.

Is UNIX used primarily with mainframes as a network operating system?
No. Licensed Unix implementations are a proprietary flexible general purpose operating system originally marketed for minicomputers and mid-range computers to support multiple users and tasks. When Personal Computers became available, versions of Unix were created for them. Unix was also implemented for the IBM mainframe. This is not the same as Linux which is an open source free system with many of the same capabilities and look & feel of unix but without the licensing requirement of unix.
