Response time refers to the duration it takes for a system or individual to react to a stimulus or request. In technology, it often measures how quickly a computer or application processes a command, impacting user experience. Shorter response times are generally preferred, as they indicate efficiency and effectiveness. In emergency services, response time is critical, as it measures how quickly help arrives after a call for assistance. For instance, ambulance services aim for rapid response to ensure patient care and safety. Reducing response time can save lives and improve outcomes in urgent situations.
