4. What is Linux
ïź
UNIX like Operating System
ïź
Multi-user, Multitasking,
Multiprocessor
ïź
Has the X Windows GUI
ïź
Runs on multiple hardware
platforms
ïź
Source Code is available
5. History of Linux
ïź
In 80âs, Microsoftâs DOS was the dominant
OS for PC
ïź
Apple MAC was better, but expensive
ïź
UNIX was much better, but much, much
more expensive. Only for minicomputer for
commercial applications
ïź
People were looking for a UNIX based
system, which is cheaper and can run on PC
6. History of Linux
ïź
Both DOS, MAC and UNIX were proprietary, i.e.,
the source code of their
kernel is protected
ïź
No modification is possible without paying high
license fees
ïź
A famous professor Andrew Tanenbaum developed
Minix, a simplified version of UNIX that runs on PC
âMinix 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
ïź
Linux has been used for many computing
platforms like PC, PDA, Supercomputers, ...
ïź
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.
12. Open Source Software
ïź
When programmers on the Internet can read,
redistribute, and modify the source for a
piece of software, it evolves
ïź
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
ïź
Download it from the Internet
ïź
But ?? first choose your
Distribution
15. Linux distros
ïź
As Linux is open source so any one can develop
his own version.
ïź
Linux distros varies in Applications provided
with each.
ïź
Market imposed on us some distros as standard
(Redhat, Debian, Slackware).
ïź
Most of current distros are based on
Debian(Ubuntu) or Redhat (Fedora).
17. Which is Suitable for Me?
ïź
Redhat is good for enterprise work.
ïź
Slackware is intended for Advanced
professional users.
ïź
Mandriva is very good for non technical user.
ïź
Opensuse is good for training usage
ïź
Fedora is good for personal use and developing
ïź
Debian is good for professional end-users.
ïź
Ubuntu is suitable for ALL !!!
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
23.
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,
27. Update with few clicks !!
Just like Windowsâ 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 youâre having a
problem with Linux, help is as close as the
nearest message board.
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 userâs own choice
