OK, What is UNIX?

Possible Operating System Designs:

	One User	Many Users
One Task/User	DOS	VM, MVS (mainframe OS's)
Many Tasks/user	NT, Win2K, OS/2 (Win95/98)	UNIX

UNIX was designed by Bell Labs

in the early 70's, along with the C language.

First practical multi-user, multi-tasking system.
Rapidly adopted by universities, large corporations.
Used to develop (and still runs) the Internet.
Implemented on everything from Cray to Apple.
Several "flavors", slightly different:

System V (Bell Labs)
BSD (Berkeley)
Proprietary - AIX, Solaris, HPIX, etc. (Mostly varieties of BSD)
Linux (closer to System V, some features from BSD)
