answer:Your media depends on your point and how you want to display your point. Do you have any graphics you need to illustrate your point? I hope so. Do you plan to display text on a screen and read it? I hope not. The only displays you have should support what you say. You should never read anything to an audience. You must always speak to the audience and tell the story, using any materials you need to illustrate the story. If you are allowed to use a computer screen or a projector, then it doesn’t matter whether you have powerpoint or a slide projector or whatever. Almost every piece of software can display images on the screen and that is no different from powerpoint. If if were you, I would use whatever software you know. I would prepare slides as jpegs and then use my slide viewer to project them on the screen. Facebook, Google+, the many picture websites, gmail, and on and on can all display slides and documents and whatever you want on your screen and on the projector. That part doesn’t matter. What matters is what slides you plan to use. That’s what you need to worry about.
