timeline of operating systems?

Hi friend,

It's a nice research in the current generation. Because operating systems are playing a vital role in today's life. Everything is dependent on the software and operating system is tha platform for all the software.

Here is the timeline of operating system :

1969 : Unix, When AT&T took one decision to abandon the Multics (Multiplexed Information and Computing Service) operating system from its minicomputers, Ken Thompson and Dennis Ritchie come together and builded one operating system so they could continue to play a space travel game that Thompson had developed, and the operating system was Unix.

1981 : The IBM PC is born, and PC-DOS and its alter ego, MS-DOS.

1983 : Richard Stallman announces the plan for GNU, a Unix-type operating system that contains no proprietary software. Twenty-six years later, GNU's official kernel, GNU Hurd, will still be incomplete.

1985 : Microsoft windows 1.01 released.

1986 : GEOS released.

1987 : Microsoft OS2.

1988 : IBM OS2 1.1

1990 : Windows 3.0

1991 : Linux

1993 : windows NT

1995 : Windows 95

1996 : Mac OS

2001 : Mac OS X

2002: XP Service Pack

2004: XP Service Pack 2

2006: Windows Vista

2008: Vista Service Pack 1 and XP Service Pack 3

2009 : Windows 7

2011 : Windows 8 will be introduced.

Hoping that you are satisfied with my answer thank you.
