BSD (Berkeley Software Distribution) and System V (System Five) are two primary variants of UNIX. AT&T and Bell Labs were the original creators of UNIX, but they are not variants. Sun and DEC are companies that produced their own UNIX-based operating systems, but they are not primary variants. Debian and Fedora are distributions of the Linux operating system, which is UNIX-like but not a primary variant of UNIX.
