History And Modern Uses Of The Unix Operating System (including embedded devices and mobile phones). Presented by Tanna Lin PTADipMgt17 Overview What is Unix? Brief History In the Present Day In Conclusion
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!
