Getting started with Linux

 Getting started with Linux
 ============================
  UNIX -> Bell LAB (1969)- Dennis Ritchie
       -> Based on "C" Language

  UNIX Distribution:
  ------------------
=> IBM - AIX
  => HP - HPUX
=> SUN - SUN Solaris
=> UNIX-BSD

1969 - UNIX was Devloped, Ken Thompson and Dennis Ritchie
1971 - First edition of Unix released 11/03/1971.
1983 - AT&T is splitted -> It can sell software
1983 - The GNU project is first announced by Richard Stallman

A program is free software if the program's users have the four essential freedoms:
===================================================================================

=> The freedom to run the program as you wish, for any purpose (freedom 0).
=> The freedom to study how the program works, and change as you wish (freedom 1).
=> 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.

1986 - HP-UX 1.0 released.

  Why Linux:
 ----------
 -> Security
 -> Free and Opensource
 -> 10x Times Faster Thand Windows
 -> Lighter
 -> Virusless
 -> Crash Less
 -> Low Hardware Requirements
 -> Multiuser System & Multitasking System
