A presentation can achieve a number of things that a written communication cannot accomplish. A presentation draws the audience and the speaker together, in terms of ideas and individual personalities, mostly in meetings, lectures, and seminars. Through the process of direct communication, the audience gets to respect the speaker for her or his ideas and the knowledge that he or she has about a certain subject (Alberts, Nakayama, & Martin, 2015).

A presentation manages to reach the hearts of the audience (Alberts et al., 2015). This is because it mainly incorporates aspects of art such as short speeches, dramatizing, and singing. For example, in a presentation that is organized for ill people or people who are dying of hunger, well-wisher may be touched to offer donations to buy medical equipment, medicines, and food by just singing about poverty and hunger.

A presentation is able to create a picture in the minds of the audience (Alberts et al., 2015). It often incorporates non-verbal communication. Whenever a speaker is stressing on a certain point, he or she makes use of gestures, such as hand movements. This non-verbal communication helps the audience to understand the context more through the creation of a mental picture.

Through a presentation, the audience can easily probe the speaker to clarify certain points. The public at the presentation consists of not only literate, but also illiterate people. The illiterate audience requires special attention such as further interpretation so that they can understand the message. Therefore, a presentation gives them that chance.

Written communication has many disadvantages compared to a presentation. It is more time-consuming than the oral presentation, and also is harder to understand sometimes (Alberts et al., 2015). Written communication costs more time for both the writer and the reader. It takes less time for a speaker to prepare the presentation and present it. In addition, the content of a presentation is summarized, hence a listener only needs less time to understand the idea compared to written information. Moreover, during a presentation, a person who doesn’t understand the content can easily probe for further explanation. On the other hand, written communication does not make sense for an illiterate person unless there is someone else to explain the content.

Written communication is also more expensive compared to oral presentation (Alberts et al., 2015). It requires a great deal of resources such as a pen, ink, paper, computers, printers, and typewriters. A lot of people may be required to prepare written assignments, and these aforementioned materials needed to do it can make written communication more expensive. This distinguishes it from the oral communication, where a presenter only needs material for and a little time for preparation.

There are certain things that I can learn as a speaker. Firstly, I should make use of non-verbal communication more often. It makes it easier for the audience to understand the idea. Apart from that, it makes my presentation more interesting, in such a way that the audience gets neither bored nor sleepy. Secondly, I should always give my audience a chance to comment, and also probe further on unclear points. Feedback from the audience offers a platform for the improvement of future presentations. They can also be used to gauge the level to which the public has understood the material. Giving the people a chance for probing further helps them to understand difficult points.
