UNIX was written in the ["C"] language, and was the first operating system to allow ["multitasking"], or the simultaneous running of separate applications. UNIX is also used on computers linked to a network and a mainframe, such as university computers. It is also a useful operating system for the development of other applications. UNIX is a popular operating system, primarily for engineering and manufacturing firms, as well as academic institutions. There are also several different types of the UNIX system, which were developed in different places, and the different versions are rarely completely compatible with each other. The Internet iself was originally designed for computers running UNIX. (See ["Platform"].) Varieties of UNIX include both ["CLI"]- and ["GUI"]-based interfaces.</span> </td> </tr> </table> </div>
