I am a second year undergraduate computer science student and I have to give a 1 hour presentation (interactive session) about Linux in general and Ubuntu in specific for first year students of my department. The audience is unlikely to be aware of power of Linux and it will be more or less an alien concept for them. I myself started using Linux an year ago when one of our seniors gave a similar presentation about it to us and so I want it to be a good and educating experience for them as well. The focus will be on Linux and not Ubuntu itself.
The following is my plan of the presentation. Please point out if I may have missed out anything important or worth mentioning. Plan
PS: It might not be the right place to ask such a question but I am myself not an expert in the field and need guidance from others to make it a presentation that will encourage them to use Linux. I shifted the question from askubuntu.com to here on advice of a user.
