5. What is Free software?? " Free software " is a matter of liberty, not price. To understand the concept, you should think of "free" as in "free speech," not as in "free beer. " http://fsf.org

6. Free software is a matter of the users' freedom to run, copy, distribute, study, change and improve the software. More precisely, it means that the program's users have the four essential freedoms: The freedom to run the program, for any purpose (freedom 0). The freedom to study how the program works, and change it to make it do what you wish (freedom 1). Access to the source code is a precondition for this. The freedom to redistribute copies so you can help your neighbor (freedom 2). The freedom to distribute copies of your modified versions to others (freedom 3). By doing this you can give the whole community a chance to benefit from your changes. Access to the source code is a precondition for this. http://bit.ly/ FreeSW

Almost all the Distros have Live CD which means you can just Plug and Boot i.e. The whole OS runs on RAM i.e. your Hard Disk untouched. Over 300 Distro exist more info at the URL below! http://distrowatch.com

10. http://bit.ly/ OpenMissesFree Open Source When we call software “free,” we mean that it respects the users' essential freedoms: the freedom to run it, to study and change it, and to redistribute copies with or without changes. http://fsf.org Open source is a development method for software that harnesses the power of distributed peer review and transparency of process. The promise of open source is better quality, higher reliability, more flexibility, lower cost, and an end to predatory vendor lock-in. http://opensource.org Free vs

11. Why FOSS and GNU/Linux ?? (1) Freedom matters Power to User Free of Charge (mostly but not neccessary) Economical No Vendor Lock-in Based on Open Standards (odt, png, svg ..) No need of Anti-Virus Most of them are Cross Platform Most companies use FOSS tool even if they produce non-foss product (Ex. java tools) Fastest Super Computer to Server of google to mobile and your Airtel Beetel router use Linux Supports 100+ file systems Schedule jobs using crond No need to Reboot after installing softwares http://bit.ly/ 101Reasons

12. Why FOSS and GNU/Linux??(2) No need to install extra Device drivers Multiple Workspaces Desktop full of eyecandy w/ 3D Compiz Desktop and KWin Most Documented OS No more Blue Screen of Death (BSOD) Both Community Support and Commercial Support available Linux is in embedded devices. Easy to Install and Use Linux now used in Mobiles too(Ex. OpenMoko, Android, Maemo,Bada etc.) GeeXbox - A 19MB OS which is a Home Theater based on Linux No Need to buy Pirated versions, Trials etc. No need to use obsolete tools. S/W with latest standards (Ex. Firefox supports HTML5) Highly Secure Built in virtualization (Xen,KVM,Virtual Box etc.) http://bit.ly/ 101Reasons
