A keynote presentation is a significant speech or talk delivered at a conference or event, often setting the tone for the gathering. It typically features a prominent speaker, such as an expert or thought leader, who shares insights on a specific topic related to the event's theme. The goal is to inspire, inform, and engage the audience. Keynote presentations are usually scheduled at the beginning of an event and can cover various subjects, including technology, business, or social issues. They often include visual aids, such as slides or videos, to enhance understanding and retention of the information presented.
