An educational talk, also known as a LECTURE, is a form of communication in which one person, typically an expert in the field, speaks to a group of people about a specific topic. The speaker typically provides information, explains concepts, and shares ideas with the audience. Lectures are often used in educational settings, such as classrooms, to help students learn and understand a subject. They can also be used in professional settings, such as conferences, to share new research or industry trends.
