Powerpoint is a good program to use for a presentation because it allows the listeners to have a visual of the subjects the speaker is talking about. It also gives the speaker a reference point for the subjects that make up the majority of the presentation.
Powerpoint has taken the place of projection slides and large white boards. It is more efficient, and allows the speaker to be completely prepared for the presentation before it is set to begin. The speaker can change the look of the slides easily, and can access the information from nearly any computer as long as an external file drive is used to save the presentation.
The Powerpoint presentation can be plugged into a computer that is then attached to a projector. The projector enlarges the presentation and can help all of the listeners see what is going on in the presentation. This visual idea can help the speaker get his or her point across over a wide audience.
Powerpoint presentations can also be used for virtual presentations. The speaker can send the Powerpoint file to the people he or she wants to speak to, thereby enhancing the conversation while the audience is looking at the slides.
