UNIX
UNIX is the trademarked name of the multiuser, multitasking, time-sharing operating system developed at AT&T's Bell Labs in 1969. Many websites are maintained on servers running a UNIX operating system, although many now run on Windows and Linux systems as well. While technically the name UNIX refers to only a few trademark-licensed versions, it is often used to refer to the many versions currently available on the market. The differences to the user are slight.
