How does quality of service help a network support a wide range of applications and services?

Quality of Service (QoS) enhances network performance by prioritizing traffic based on the specific needs of various applications and services. By managing bandwidth allocation, minimizing latency, and reducing packet loss, QoS ensures that critical applications, such as real-time voice and video, receive the necessary resources to function effectively. This prioritization allows for a more reliable user experience across diverse applications, ultimately supporting a wider range of services without degradation in performance.
