A lightning talk is a very short presentation lasting only a few minutes, given at a conference or similar forum. Several lightning talks will usually be delivered by different speakers in a single session, sometimes called a data blitz.
The goal of lightning talks is to articulate a topic in a quick, insightful, and clear manner. These concise and efficient talks are intended to grab the attention of the audience, convey key information, and allow for several presenters to share their ideas in a brief period of time
It is also a great way to increase your communication skills and gradually get the hang of conducting yourself in public speaking.
