In a network where the communication channel is shared by all the machines, this model is referred to as a “broadcast channel” or a “shared medium” type of communication. This approach is typical in several types of networks, including:
1. Local Area Networks (LANs): Particularly in earlier or simpler implementations like those using Ethernet technology in a bus topology or a hub-spoked topology, where all the machines are connected to a single cable (in the case of a bus topology) or a central hub (in the hub-spoked topology) which serves as the shared communication channel.
2. Wireless Networks (Wi-Fi): In wireless LANs (WLANs), devices communicate over the airwaves, sharing the same frequency band. This is a perfect example of a shared communication channel where the Wi-Fi access point serves as the central point of communication, and bandwidth is divided among the devices.
3. Broadcast Radio and TV: Though not a computer network, this is another form of a shared communication channel where one transmitter sends signals over a broad area, and any number of receivers within range can tune in to the broadcasted content.
In such networks, mechanisms like Carrier Sense Multiple Access with Collision Detection (CSMA/CD) for Ethernet networks or Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) for Wi-Fi networks are implemented to manage the access to the shared medium. These mechanisms help to prevent data collisions by controlling when and how devices can transmit
