Linux is a type of kernal, of which operating systems are based upon. Linux itself is based on unix which was originally created by the millitary to store Top secret information securely. this is why linux contains very little holes, cannot get viruses and is nearly impossible to hack. That apart, the operating system itself is alot more secure thats why many hosts choose to use Linux as their main OS.

The linux server is exactly the same as the windows server only created for the linux binary.
