This document provides an introduction to Linux, including: 1. It defines Linux as a UNIX-like operating system that is multi-user, multitasking, and runs on multiple hardware platforms. 2. It discusses the history of Linux, including its origins in 1991 when Linus Torvalds developed the initial Linux kernel version 0.0.1 at the University of Helsinki. 3. It notes that today Linux is used widely for computing platforms like PCs, supercomputers, and more, and provides graphical user interfaces as well as command line interfaces.

3. What is Linux ?

4. What is Linux

UNIX like Operating System

Multi-user, Multitasking,
Multiprocessor

Has the X Windows GUI

Runs on multiple hardware
platforms

Source Code is available

5. History of Linux

In 80’s, Microsoft’s DOS was the dominant
OS for PC

Apple MAC was better, but expensive

UNIX was much better, but much, much
more expensive. Only for minicomputer for
commercial applications

People were looking for a UNIX based
system, which is cheaper and can run on PC

6. History of Linux

Both DOS, MAC and UNIX were proprietary, i.e.,
the source code of their
kernel is protected

No modification is possible without paying high
license fees

A famous professor Andrew Tanenbaum developed
Minix, a simplified version of UNIX that runs on PC
–Minix is for class teaching only. No intention for
commercial use

7. History of Linux
In Sept 1991, Linus Torvalds, a second year
student of Computer Science at the University of
Helsinki, developed the preliminary kernel of
Linux, known as Linux version 0.0.1

8. Linux Today

Linux has been used for many computing
platforms like PC, PDA, Supercomputers, ...

Not only character interface but also user
interface is available

9. Linux Today
The Oak Ridge National Laboratory's Jaguar
supercomputer, as of November 2009 the
world's fastest supercomputer. It uses the Cray
Linux Environment as its operating system.

10. Linux Today

11. But what we mean by
Open Source ?!

12. Open Source Software

When programmers on the Internet can read,
redistribute, and modify the source for a
piece of software, it evolves

People improve it, people adapt it, people fix
bugs. And this can happen at a speed that,
compared to conventional software
development, seems astonishing

13. How we can get it

Download it from the Internet

But ?? first choose your
Distribution

14. Distribution !!!!?

15. Linux distros

As Linux is open source so any one can develop
his own version.

Linux distros varies in Applications provided
with each.

Market imposed on us some distros as standard
(Redhat, Debian, Slackware).

Most of current distros are based on
Debian(Ubuntu) or Redhat (Fedora).

16. Popular Linux Distributions

Archlinux,

CentOS

Debian

Knoppix, a Live CD

Red Hat Enterprise Linux

Ubuntu

Fedora

17. Which is Suitable for Me?

Redhat is good for enterprise work.

Slackware is intended for Advanced
professional users.

Mandriva is very good for non technical user.

Opensuse is good for training usage

Fedora is good for personal use and developing

Debian is good for professional end-users.

Ubuntu is suitable for ALL !!!

20. Why you should use Linux

21. Forget about viruses
Security has always been the number one priority
with Linux
Linux has a robust security system
There do not exist viruses for the Linux platform

22. Is your system is unstable !!
Have you ever lost your precious work because
Windows crashed? Have you ever gotten the "blue
screen of death" or error messages telling you
that the computer needs to be shut down for
obscure reasons?
Crashes or freezes are not prevalent in Linux

24. Linux is free
Linux is free and always will be as
compared to the very costly Windows and
Mac OSX
Using pirated Windows is a bad thing

25. Linux comes with software built it
When the system has installed,
why would you still need to
install stuff ?
Common software such as
music player, web browser,
video player, image editor,

26. Linux comes with software built it

27. Update with few clicks !!
Just like Windows’ Update tool, Linux has a more
better alternative to it to update all your system
in a few clicks

28. Linux does not get slow
As Linux is impervious to viruses,
trojans,
spywares, which are the main reasons
to
slow down the PC, systems based on it
do not get slower
Linux consumes lesser system
resources

29. Linux can run on older hardware
Windows requires more
and more hardware
power as its version
number increases (95,
98, 2000, Me, XP, etc.).

30. Support is everywhere
If you’re having a
problem with Linux, help is as close as the
nearest message board.

31. And more , more , more ,
more …..

32. Why not to switch to linux ?

33. Why not to switch to linux ?
If you are using any propriatory software
which is not supported by Linux
If you are using any hardware which is not
supported by Linux

34. Comparison between Linux and windows
I don't like to talk about this topic
You have to try with yourself and tell me
What you see :)

35. Conclusion
So, what OS a user should opt to choose?
The answer depends on user’s own choice
