What is the difference between essay and presentation?
Both are means of displaying information. The essay is more driven by writing and the written word becomes critical in this format. A presentation is much more fluid and can be interpreted in a variety of ways. There can be a great deal of variance in final product of a presentation, using verbal, dramatic, question and answer, technological or other modes of communication. Unless specified by an instructor, there is less in way of specific formal guidelines as opposed to an essay, which is much more strictly defined and whose conventions are shared on a larger level.
The main difference is that essay refers to a written piece of work, while presentation refers to information provided by a presenter to a group of people. As used originally, the presentation always referred to the presentation made by a real person. But now, visual or audio visual recorded presentations are also called presentation. Also such recorded material itself is called presentation.
Further, essays are usually short and deal with non fictional subjects and present writers opinion or analysis. Presentations have much wider scope, both in terms of the length of presentation and the subjects covered. Presentations are used widely in the field of business, science, and academics as an aid to sharing information, and to support or acceptance of the audience in desired ways.
If you want to compare two things, they should have certain links, either hidden or over, to make criterions for the comparisons.
Basically, both essay and presentation are the ways in which we can express our opinions, ideas to other people.
However, essay is a written work, while presentation is accompanied by literally, presentation.
You have to have main argument, evidence, explanation in your essay, but in case of presentation, you can just write the main points and explain the details verbally.
