2. LINUX INSTALLATION
 Linux is freely available operating system. You can download
any of the distribution from CentOS, Fedora and if you have
very low end system you can go with DSL (Damn Small Linux)
 At the beginning level I would suggest you to start installing
and using Linux on virtual machine, once you are comfortable
with operating system you can move to install it as primary or
secondary operating system.

 Password must have atleast 6 characters (This can be bypassed but
