welcome to linux

  1. 1. Using Pirated copy of Operating System??? Busy to remove Viruses??? Problem with Unknown Application???
  2. 2. It's time! Kiss the Blue Screen of Death. Say "Goodbye" to Windows crashes, viruses, hassles, & ohh! yah costs! Moving to Linux
  3. 3. Welcome to Linux <ul><li>Linux is a clone of UNIX. </li></ul><ul><li>It was created by Linus Torvalds in 1991 </li></ul><ul><li>What is Linux </li></ul><ul><ul><li>Linux is a kernel, the brains or control center of a collection of software packages, usually referred to as a Linux distribution. </li></ul></ul>
  4. 4. The GNU GPL <ul><li>Linux is distributed under the GNU General Public License. </li></ul><ul><ul><li>in essence, the GPL says that anyone may copy, distribute, and even sell the program, so long as changes to the source are reintroduced back to the community and the terms of the license remain unaltered. Free means that you are free to take Linux, modify it, and create your own version. Free means that you are not at the mercy of a single vendor who forces you into a kind of corporate servitude by making sure that it is extremely costly to convert to another environment. If you are unhappy with your Linux vendor or the support you are getting, you can move to the next vendor without forfeiting your investment in Linux. </li></ul></ul><ul><ul><li>In other words, &quot;free as in speech&quot;, or simply &quot;freedom&quot;. </li></ul></ul>
  5. 5. What do you gain? <ul><li>No operating system will ever be perfect, but Linux is getting pretty close. With Linux, you'll gain : </li></ul><ul><li>Better Security </li></ul><ul><li>Increased Stability </li></ul><ul><li>Power from your OS </li></ul><ul><li>Money (saved!) </li></ul><ul><li>Freedom from legal hassles </li></ul>
  6. 6. What do you lose? <ul><li>Hardware and peripheral support </li></ul><ul><ul><li>Some hardware is designed to run exclusively with Windows (eg: Winmodems). Linux developers continue to work on drivers </li></ul></ul><ul><li>Shrink-wrapped software. </li></ul><ul><ul><li>Hot new games or popular packages may not be available at your local software store. Still, thousands of packages exist for Linux a click away. </li></ul></ul><ul><li>A step into the unknown. Learning curve . </li></ul><ul><ul><li>Even moving from 95 to XP will take some retraining. </li></ul></ul>
  7. 7. What about support? <ul><li>Corporate support through large vendors like Red Hat, SuSE, Mandrake, HCL, IBM, HP, and others. </li></ul><ul><li>Worldwide community support : IRC chats, Linux User Groups, mailing lists </li></ul><ul><li>Linux Documentation Project </li></ul><ul><ul><li>http://www.tldp.org </li></ul></ul><ul><li>HOWTOs, man pages, books etc. </li></ul><ul><li>Linux technical support &quot; among the best &quot; </li></ul>
  8. 8. Getting Linux <ul><li>encourage you to use free and open source software, improve it and pass it on. </li></ul><ul><li>Is Linux really FREE? </li></ul><ul><ul><li>TANSTAAFL (Robert A. Heinlein) </li></ul></ul><ul><ul><li>A free download will still cost you connection time on the Internet, disk space, time to burn the CDs, and so on. </li></ul></ul><ul><ul><li>&quot;Free as in speech&quot; </li></ul></ul><ul><ul><li>&quot;Free as in beer&quot; </li></ul></ul><ul><ul><li>Distributed under the GPL </li></ul></ul>
