Many MNCs like google supports FOSSHandles 100+ file systems
Why Open Source ? (contd.)Excellent for prgramming Linux used in embedded systems (e.g. Arduino kits)3D Desktop – Compiz Fusion It is easy to get softwareNo need of extra device patches, and they are free. drivers 95% server are on linuxPurpose based distribution available in markets Less attacks on LinuxNo More BSOD Mobile devices also using linuxMultiple Workspaces (upto 36 in Ubuntu) - Android Based devices - Maemo ( Nokia)
Free Software FoundationRMSRichard Matthew StallmanFounder of GNU in 1983Started FSF in 1985Started making GNU OSGNU refers to GNUs Not UnixReleased GNU GPL licenseReleased concept of copyleft
Free Software PhilosophyFree software is a matter of the users freedom to run, copy, distribute, study, change and improve the software. More precisely, it refers to four kinds of freedom, for the users of the software: 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 improve the program, and release your improvements (and modified versions in general) to the public, so that the whole community benefits (freedom 3). Access to the source code is a precondition for this.http://www.gnu.org/philosophy/free-sw.html
General Public License (GPL)GPL and many Free Software licenses are Copy leftCopyLeft is legal mechanism to protect the modification and redistribution rights for free softwareGPL v2.0 and GPL v3.0 availableMost popular licenseProvides flexiblity to a code
