Presenting is the act of formally communicating information to an audience of one or more other people, usually large groups. Presentations are used to inform, motivate, persuade, or even entertain people and oftentimes are formatted as lectures, speeches, or demonstrations. A person can present in a variety of ways, but usually they stand on a stage or simply at the front of a room before the audience, and may use technology or physical artifacts to help convey information further. Presenting is a critical activity common throughout schooling, where teachers and professors give presentations as a form of teaching, and where students even learn how to present. Presenting is also an important skill in many professions, particularly in business-related fields.
