Slide 1 : UNIX HISTORY:
first version in 1969.
everything is file.
small single purpose program.
configuration data stored in text.
avoid cative user interfare.
ability to chain program together to
perform complex tasks.
Slide 2 : GNU/FSF (GNU – GNU is Not Unix)
GNU project started in 1984.
goal : create “free “ Unix clone.
By 1991 . nearly all required
applications created.
Free Software Foundation.
Non- profit organisation that
manages the GNU project.
Fedora Project Started and funded by
Redhat.
Slide 3 : GPL-GNU (GENERAL PUBILC LICENCE )
Primary License for Open Source Software
- Encourages Free Software.
- All enhancements and changes to GPL
software must also be GPL.
Often called “copyleft”
- “All rights reversed”
A few applications have their own licensing
agreements.
Software Developers who use code from
BSD (Berkeley Software Distribution) must
be agree to abide the terms of BSD
(http://www.bsd.com).
Slide 4 : Who Needs Open Source? Any organization or user who wants to
customize applications as per their
requirements.
Software professionals who want to
improve their knowledge base by
understanding the application codes.
Application developers who want to
serve the community by providing the
source code of their applications.
Slide 5 : LINUX ORIGIN :
Linux basically a OS that developed
by the Linus Torvalds.
Finnisd college student in 1991
created Linux kernel.
when Linux kernel combined
with GNU application complete free
Unix like OS possible.
Slide 6 : WHY LINUX:
In a nutshell, using an open source OS allow you following benefits :
an option to choose and modification.
relatively inexpensive solution.
a secure and stable OS.
Linux is a Unix like operating system
multi-user and multi tasking
Several organizations are offering OS services built
around Linux. Important among these are:
Redhat
Suse

Slide 7 : ABOUT MARKET :
Redhat is having largest market share in
Global Linux Market. (65%)
67% of Telecom and BPO and 50% of
healthcare industry run on Linux in
India.
Highly secure, reliable, scalable and
cost effective operating system.

2-6 GB DISK SPACE.
486 DX4/100 WITH 32 MB OF RAM
TO MAINFRAME COMPUTER.
Slide 9 : WHY SHOULD I USE LINUX OS :
HARDWARE :GREATER VARIETY.
BETTER EFFICIENCIES.
SOFTWARE : REDUCED COST.
OPERATION : LOWER RUNNING
COST.
Slide 10 : HIGHLIGHTING FACTORS:
Modular & Flexible.
Secure, Sturdy, Stable & Robust.

Messenger, and a lot more).
Networking.
Multimedia (Audio-players Video-
players)
Graphic creation tools, Games, and lot
more.
Slide 12 : YOUR BENEFITS:
Total Cost of Ownership
(TCO) benefits :
It reduces upto 80% of your
operating cost.
NO danger of illegal work
(pirated software).
