The document provides a history of operating systems, beginning with the creation of UNIX at Bell Labs in 1969. It describes how UNIX was rewritten in C in 1973 and some of its key authors. It discusses the development of commercial Unix systems, BSD, and Linux and major distributions like Slackware, Debian, and Red Hat. It also references the GNU project and development of the GPL license, and how these led to the rise of free and open source software.
Here it is some of brief history of operating system and also it shows how there came revolution in the industry of technology regarding operating system
differences between unix and linux:
Some people think Unix and Linux as synonyms, but that's not true. Many operating systems were developed to be like Unix but none of them got the popularity as Linux. Linux is the clone of Unix. It has several features similar to Unix, still have some key differences let us see in the presentation..

An operating system (OS) is a collection of software that manages computer hardware resources and provides common services for computer programs. The operating system is an essential component of the system software in a computer system. Application programs usually require an operating system to function.
Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources.
For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware,[1][2] although the application code is usually executed directly by the hardware and will frequently make a system call to an OS function or be interrupted by it. Operating systems can be found on almost any device that contains a computer—from cellular phones and video game consoles to supercomputers and web servers.
Examples of popular modern operating systems include Android, BSD, iOS, Linux, OS X, QNX, Microsoft Windows,[3] Windows Phone, and IBM z/OS. All these, except Windows, Windows Phone and z/OS, share roots in UNIX.
Presentation Regarding functions of operating systems and their working and other information regarding their uses and types. Useful for Students and other for knowing better about them.

Evolution of Microsoft windows operating systemsSai praveen Seva
A presentation regarding the evolution of operating systems developed by Microsoft corporation..... i have searched for such presentation on the internet but couldn't find one. So I chose to make one
A ppt on Mac Operating System by Apple. I've made this presentation simpler by changing the words in it to a simpler English which everyone can understand and explain it easily. For getting customized projects on Information Technology, contact at https://quvor.com
In the presentation I have tried to cover the Evolution of Linux as an Operating System. The most of the content used is freely available on Internet , I have just tried to streamline it and summarize it as cleanly as possible from my point of view. Any improvements, suggestions, comments are most welcom.
This lecture goes into basic info about Linux and the GNU Project.

GNU, Apache, PHP, Mozilla, Ubuntu, Wikipedia, LibreOffice -- Today, there are hundreds of open source groups, each with its own culture, methodology, and governance model.
How are these groups alike?
How are they different?
Is there one true path to open source enlightenment,
or do many paths converge around a common singularity?
Join open source insider Ted Husted as we look behind the curtain to see who's pulling strings that steer your favorite open source projects.
How to implement PassKeys in your applicationMarian Marinov
PassKeys is relatively new way of authentication. This presentation aims to provide a bit of guidance on how you can implement them in your own application.

4. So, WHO created UNIX?
➢ Developed in 1969 by AT&T at Bell Labs
➢ Peter Neumann coined the project name
Unics - UNiplexed Information and
Computing Service
➢ Written in Assembly
➢ 1973 - rewritten in C
➢Authors
➢ Ken Thompson
➢ Dennis Ritchie
➢ Brian Kernighan
➢ Douglas McIlroy
➢ Michael Lesk
➢ Joe Ossannas with UNIX :)
5. A little bit more about the Authors
➢ Ken Thompson & Dennis Ritchie wrote C
➢ Brian Kernighan wrote the first book for C
he is also the K in the AWK programming
language
6. Unix history
1982, System III – first commercial Unix
1982, The beginning of the GNU movement
Jan 1983, System V Release 1
Apr 1984, System V Release 2
Apr 1984, System V Release 3
Jun 1983, X Window system was born
7. The giants of UNIX
1978 – Berkeley Software Distribution(BSD)
1980 – Microsoft created Xenix licensed by AT&T
1982 – Sun Microsystems create SunOS out of BSD
1983 – Xenix is acquired by
Santa Cruz Operation(SCO) and renamed to
SCO UNIX
1995 – BSD splits into FreeBSD, OpenBSD and
NetBSD
2001-2003 – Only Sun Solaris, HP-UX, IBM AIX and
SGI IRIX were still going
10. Why FREE?
1956 – antitrust settlement forbids AT&T to
enter in the computer business
60s – MIT, AT&T Bell Labs, General Electric
create the Multics time sharing OS
May 1975 – ARPA documentation of Unix
time-sharing systems in RFC 681
11. Software wars
The feedback we have gotten from the hundreds of
people who say they are using BASIC has all been
positive. Two surprising things are apparent however.
1) most of these “users” never bought BASIC (less
then 10% of all Altair owners have bought BASIC),
and 2) The amount of royalties we have received
from sales to hobbyists makes the time spent on
Altair BASIC worth less then 2$ an hour.
Why is this? As the majority of hobbyists must be
aware, most of you steal your software. Hardware
must be paid for, but software is something to share.
Who cares if the people who worked on it get paid?
13. The response
Open Letter to Hobbyists
Sep.1983 – The GNU Project was announced
Richard Stallman – the father of Free Software
1989 – The GPL license was written by Stallman
Feb.1998 – Open Source Initiative
Eric S. Raymond – The Cathedral and the
Bazaar
14. The response
Between 1984 and 1990 a lot of Free software was
created:
➢ GNU coreutils - ls, cat, cp, mv, rm
➢ GNU binutils - as, ld, ldconfig
➢ GNU build system - Automake, Autoconf,Libtool
➢ GNU Compiler Collection(GCC) - compilers for
C, C++, Fortran, Ada and Java
➢ GNU Debugger -gdb
➢ GNU C library - glibc
➢ Bash - unix shell
➢ Emacs - text editor
➢ и много други.
