Multipoint links are communication connections that allow multiple devices to share a single communication channel. This setup is commonly used in networks where several users need to send and receive data simultaneously, such as in Wi-Fi networks or telecommunication systems. Each device can communicate with others without needing a direct connection to each one, making it efficient for resource sharing. In a multipoint link, data is transmitted to all connected devices, which can then respond or send their own data back. This type of link is essential for applications like video conferencing and online gaming, where many participants interact in real-time over the same network.
