Abstract:

Understanding network latency is essential in education, as it helps students grasp the complexities of modern communication technology. Network latency, which refers to the delay in data transmission over a network, is influenced by factors such as physical distance, technical infrastructure, and network congestion. Despite its importance, this concept often receives limited attention in educational settings, where the focus tends to be more on bandwidth as the primary measure of network quality and speed. With the advent of 5G and optical networks, which suppress the bottleneck of low data rates, low latency is now becoming the more critical factor. Future internet applications like real-time communication, cloud gaming, and autonomous vehicles require extremely low latency to function smoothly and efficiently. To make the complex concept of network latency understandable, educational demonstrators that convey abstract technical concepts in a tangible and illustrative manner are highly beneficial.

This approach utilizes physical models and interactive experiments to elucidate the dynamics of network latency. The demonstrators employ optical, acoustic, and tactile elements to create a multisensory learning experience. Optical elements, such as video transmissions, demonstrate the impact of latency on transmission quality by making delays visible in real-time. Acoustic signals, like tapping sounds or noises from moving objects, can simulate the temporal delay in data transmission, drawing attention to the timing aspects of latency. Tactile elements, such as the operation of remote-controlled cars, provide a hands-on experience where latency can be adjusted to show when and how delays significantly affect control and responsiveness.

The use of such demonstrators in computer science or informatics education, particularly for high school students, enhances a deep understanding of network technology and raises awareness of the challenges in digital communication. By incorporating haptic, visual, and auditory elements, these tools support learning by translating abstract concepts into concrete experiences. This not only facilitates comprehension but also encourages critical thinking and problem-solving skills among learners.

Overall, the experience with these educational demonstrators highlights their value as effective tools for practical and accessible technological education. This is especially relevant as the importance of network latency continues to grow in future internet applications.
