Free software" is a matter of liberty, not price. Tounderstand the concept, you should think of"free" as in "free speech," not as in "free beer"

Background of FOSS

The Four Freedoms

Use for any purpose(run a program).

Study the program(Access to the source

code).

Redistribute copies(to help others).

Improve the program and redistribute it.

The stride towards Freedom

1984 : Richard Stallman kicks off the GNUproject.

1985 : Richard Stallman startsFree Software Foundation.

1989 : Release ofGNU(GNU's Not Unix!).

1989 : Release of GNU GPL Version1.

1991 :LinusTorvaldsannouncesthe release of LinuxKernel.

Benefits of FOSS

Security

Economy and affordability No license and

maintenance fees forsoftware's.

Reliability/Stability(No crashes of System).

Noviruses.

Adaptability Can be modified to suit a particularly

locality.

Piracy.User freedoms Freedom to use, study, modify and distribute a particular software (through the GPL and open source licenses).NO Slow Down of System.

HOW BIG IS FOSS??????

How many projects?
- Certainly in 100s ofthousands.
- Over 400,000 projects registered on one site alone
(sourceforge.net).
- Similar number of developers?

How many users?
- Depends on what you call a 'user' !
- Certainly manymillions.

Some FOSS Equivalents to Proprietary Software's

Can FOSS be combined with proprietary software?

-CombiningFOSS with proprietary software ispossible, depending on the manner of combination and on the specific license of the software.
-An example of this is running anOracle databaseon aGNU/Linuxoperating system.

Popular Linux Distros

Fedora Core: Stable, secure, user friendly, easy to install. Frequent full releases.

Ubuntu Linux: The growing community distribution. Debian based but stable releases every 6 months. User friendly. Great for beginners.

Debian: Very stable and safe, but more difficult to configure and install. Developer but no user friendly yet. Stable releases not frequent enough (every 2 or 3 years). Great for servers, but not for beginners!

Mandriva Community :Easy to install, secure, user friendly, frequent full releases, but less stable (not enough testing and taking user feedback into account).
