    star network

    In a star network each device on the network has its own cable that connects to a switch or hub. A hub sends every packer of data to every device, whereas a switch only sends a packet of data to the destination device.

    ring network

    In a ring network each device is connected to two other devices - this forms a ring for the signals to travel around. Each packet of data on the network travels in one direction and each device receives each packet in turn until the destination device receives it.
