An oral presentation involves explaining information to an audience verbally. It requires skills like maintaining eye contact, engaging the audience, and presenting well-researched information within the time limit. Oral communication is used for temporary matters that require direct interaction to build rapport. Effective oral presentations include visual aids, clearly explaining the topic for the audience's knowledge level, and concluding the key points. They are commonly used in classroom lectures, business meetings, and graduation ceremonies. While oral presentations allow for confident expression, preparation and practice are important for conveying ideas clearly to the audience.
