The Presentation can be defined as a formal event characterized by teamwork and the use of audio-visual aids. The main purpose of a presentation is to give information, to persuade the audience to act and to create goodwill. A good presentation should have a good subject matter, should match with the objective, should best fit the audience, and should be well organized.
A presentation is a form of public speaking and sometimes the two terms are interchanged. However, in business practice, presentation usually means presenting your point of view on a subject orally, formally and with preparation. A presentation may be to inform, argue out your case, persuade.
