Quiz buzzers are devices used in quiz competitions to signal a contestant's readiness to answer a question. Typically, they consist of a button that participants press when they believe they know the answer. The first person to press their buzzer gets the opportunity to respond, adding an element of excitement and competition to the quiz. These buzzers can be standalone devices or part of a larger quiz system, often used in settings like schools, game shows, and trivia nights. They help ensure a fair and organized way to manage responses, making quizzes more engaging for both participants and audiences.
