Explanation

An informal presentation is a way of expressing, exposing, reporting, counting, speaking, presenting or disseminating one or more ideas and in which it is not necessary to use a specific language or related to any given science since, being informal, it must be accessible to all public, that is to say, that all the public must understand what the speaker is expressing. In addition, in most informal presentations the topics are usually related to issues of daily life or general knowledge of people, for this reason, this allows that within the speech of the speaker the words are not formal and the use of anecdotes or with humorous content. An informal presentation can be differentiated from a formal presentation, given that the second, despite having the same objective of expressing or disseminating ideas uses formal language such as technical language and includes formal conventions such as a dressing code, also this type of speeches are directed to specific publics, for example, students, scientists, workers, professors, among others.
