The document discusses Linux and open source software. It provides an overview of Linux, including that it is a Unix-like operating system that runs on multiple platforms and includes source code. It also discusses why open source software is chosen, including lower costs, greater security from many developers reviewing code, and avoiding vendor lock-in. Open source works on a "bazaar model" where many developers improve the software collaboratively.

2. What is Linux?
• Linux is a generic term referring to Unix-like graphical user interface
(GUI) based computer operating systems.
• It is Multi-user, Multitasking, Multiprocessor
• Has the X Windows GUI
• Coexists with other Operating Systems
• Runs on multiple platforms
• Includes the Source Code

3. Microsoft Open Sources .NET, Saying It
Will Run on Linux and Mac
IN NEWS!!!
Microsoft is now open sourcing
the very foundation of .NET

4. Why is it significant?
• Powerful
– Runs on multiple hardware platforms
– Users like its speed and stability
– No requirement for latest hardware
• It’s “free”
– Licensed under GPL
– Vendors are distributors who package Linux

5. Why did we choose Linux for Internet
• Was available with all necessary Internet software 6 years back
when Microsoft Windows was not ready for Internet.
• Low cost compared to any other alternative. Sun Solaris,
Novell, MS Windows, etc.
• Extremely reliable. No reboots in 450+ days.
• Easy to setup. Takes 4 easy steps to setup a mail server.
Download a CD, Burn it, Boot from it and the server is ready for
adding users and setting passwords.
• Lower hardware requirements. Pentium computer can act as a
fast mail server for 30 users.

6. Linux Provide Security
As there is a limited access
of user to basic files and folders, in Linux network it
provide security to user’s privacy. Without
disclosing the secured data Linux acts as a efficient
server.
Linux is "virus-free" in that there are
essentially no viruses for Linux in the wild,
although research viruses certainly do exist.

7. Open Source Software
• Open-source software (OSS) is computer software with its source code made
available with a license in which the copyright holder provides the rights to study,
change and distribute the software to anyone and for any purpose.
• People improve it, people adapt it, people fix bugs. And this can happen at a speed
that, compared to conventional software development, seems astonishing.

8. HOW OPEN SOURCE WORKS ?
The Bazaar model

9. The bazaar model should exhibit the following patterns:
•Users should be treated as co-developers
•Early releases
•Frequent integration
•Several versions
•High modularization
•Dynamic decision making structure

10. The top four reasons (as provided by Open Source
Business Conference survey) individuals or organizations
choose open source software are:
 Lower cost
 Security: Proprietary software forces the user to accept the level
of security that the software vendor is willing to deliver and to
accept the rate that patches and updates are released
 No vendor 'lock in’
 Better quality.
