FOSS = Free and Open source software What is FOSS? "Free software" is a matter of liberty, not price. 4 essential freedoms :
The freedom to run the program, for any purpose .
The freedom to study how the program works, and change it to make it do what you wish .
The freedom to redistribute copies.
The freedom to distribute copies of your modified versions to others .

What is an Operating System ??
An interface between users and hardware - an environment "architecture”
Allows convenient usage; hides the tedious stuff
Allows efficient usage; parallel activity, avoids wasted cycles
Provides information protection
Gives each user a slice of the resources
To ensure the system behaves in a predictable way

What is LINUX? Linux is an operating system created by - Linus Torvalds, at the University of Helsinki in Finland. The kernel, at the heart of all Linux systems, is developed and released under the GNU General Public License and its source code is freely available to everyone. Important Features : Freely distributed, Adaptability and Robustness,

Why Migrating to GNU/LINUX ?
Crashing System
Unlimited and Uncontrolled Viruses.
Unknown behavior of Operating System.
Dependability of user on Operating System Vendor.

BOOT LOADER At time of power on, system does not have an operating system in ROM or RAM. Its a small program that starts sequence of loading other programs into RAM. So its only job is to load other data and programs which are then executed from RAM.

GRUB GRUB = GNU GRand Unified Bootloader Purpose : 1. To recognize filesystems 2. Load boot images
