What is Unix™ ?



Unix™ is an open source operating system.
Unics : UNiplexed Information & Computing
Service.
Unix™ was first written for Space Travel, a
computer game by Ken Thomson. Space
Travel is the first Application created. It is
also the first computer game ever created.
Space Travel: A game
simulating travel in space.
You navigate by zooming
in/out, to reach earth or the
other planets in your
spaceship.
Brief History of Unix™

1969 : AT&T develops Multics (multiplex
information & computing science)




Multics was an experimental OS
Ken Thompson used it to play Space Travel, a game
he wrote on the Multics computer system.
Project was shelved and so did the multics system.
Ken decides to write re-work multics so he could play
Space Travel on a smaller system left unused in the
lab. Dennis made sure of that by recoding in C.
The PDP-7 system that Unix™
was written on. It even ran
Space Travel.
Brief History of Unix™

1970s: Redeveloped & recoded in C
programming by Ken Thompson & Dennis
Ritchie


AT&T recognised their work and funded them with
bigger systems. In return they created roff, a text
processing system. Final versions is troff, which does
text formatting.
Meanwhile, Dennis teaches C programming & Unix at
Berkeley University.
Brief History of Unix™




1977: Berkeley student Bill Joy releases BSD
(Berkeley Software Distribution)
1980: MACH kernel for BSD from CMU
1988: NextStep is release with GUI
1991: Linus Torvalds releases
Unix-Like Linux
RIP: Dennis Ritchie, the creator of C
programming passed away a week after
Steve Jobs on Oct 12th 2011.
He has given to us very valuable technology
and inspired developers to create.
Present Day Unix™

Workstations: Ubuntu, Gnu, Darwin,
Windows, Mac OSx, MINIX, Xsystem,
FreeBSD, Fedora, Open BSD ..


Servers: HP-UX, AIX (IBM), Solaris
(Oracle), Novell SLES, Red Hat
Enterprise Linux
Network: Cisco, Juniper
Present Day Unix™


Embedded Devices: Ezlink Card Readers,
Aircon temperature control & more
Mobile Devices: Compaq’s iPAQ, Nokia,
Motorola, Android tablets & mobile
phones, Blackberry Playbook, iPhone,
iPad, iPod, GPS system
Gaming: Nintendo DSLite, Sony
Playstation 3, Xbox 360
In Conclusion…

Unix™ has become the base for many kinds
of computing systems



Low cost - no renewals or fees per workstation
Stability - no downtime due to its multiprocessing capabilities & efficient kernel
Expandability - various hardware are supported
Development possibility
Customization - run company requirements
Networking capabilities – it is a pioneer
Unix™ is the preferred choice by companies
to run their File and Network Servers.
The End
Thank you!
