The UNIX operating system was developed by the Computing Science
Research Group at Bell Laboratories in New Jersey. An `operating system'
is basically a supervisory program responsible for managing hardware
resources, accessing files, and interacting with users. UNIX is
interactive (it allows for input commands, executes them, and
displays appropriate responses, etc.), multi-tasking (it can run
several processes at the same time), and is a multi-user
operating system (it can attend to more than one user at a time---a
natural consequence of the multi-tasking feature). For a more complete
description of the UNIX system for new users than can be described here,
refer to Introducing the UNIX System and the appropriate
man pages..
