What are the key differences between a symposium, conference, and summit in terms of their format, purpose, and level of engagement?

A symposium typically involves a series of presentations or discussions on a specific topic by experts in the field. A conference is a larger event that may include various sessions, workshops, and networking opportunities for professionals in a particular industry. A summit is a high-level meeting where leaders come together to discuss and make decisions on important issues. The level of engagement is usually highest at a summit, followed by a conference, and then a symposium.
