What is the difference between a token ring and a star network?

A token ring network is a type of local area network (LAN) in which all devices are connected in a ring topology. Each device has a token, which is a special type of message that allows the device to transmit data. The token is passed from device to device around the ring. When a device has data to transmit, it waits for the token to arrive. Once the token arrives, the device can transmit its data.

A star network is a type of LAN in which all devices are connected to a central hub. The hub is responsible for forwarding data between devices. When a device has data to transmit, it sends the data to the hub. The hub then forwards the data to the destination device.

Here is a table that summarizes the key differences between token ring and star networks:

| Feature | Token Ring | Star Network | |---|---|---| | Topology | Ring | Star | | Data Transmission | Token-based | Hub-based | | Reliability | High | Lower than token ring | | Cost | More expensive than star networks | Less expensive than token ring networks | | Scalability | Less scalable than star networks | More scalable than token ring networks |

  1. What is the main advantage of a token ring network?
    • Token ring networks are more reliable than star networks.
  2. What is the main advantage of a star network?
    • Star networks are less expensive and more scalable than token ring networks.
  3. Which type of network is more commonly used today?
    • Star networks are more commonly used today than token ring networks.
  4. What is the difference between a token and a frame?
    • A token is a special type of message that allows a device to transmit data. A frame is a unit of data that is transmitted over a network.
  5. What is the purpose of a hub in a star network?
    • The purpose of a hub in a star network is to forward data between devices.
