    Question

    What is a key characteristic of a star topology in networking?

    A All devices are connected in a circular fashion, with each device connected to exactly two others. Correct Answer Incorrect Answer
    B All devices are connected to a central hub or switch, with each device having a direct connection to this central node. Correct Answer Incorrect Answer
    C Devices are connected in a linear sequence, with each device connected to two others in a chain. Correct Answer Incorrect Answer
    D Devices are connected in a grid pattern, with multiple connections forming a mesh network. Correct Answer Incorrect Answer
    E Devices are connected in a hierarchical manner, with multiple levels of nodes and sub-nodes. Correct Answer Incorrect Answer

    Solution

    In a star topology, all network devices are connected to a central hub or switch. This central node serves as the focal point for communication within the network. Each device has a dedicated connection to the hub or switch, which helps in managing and routing data efficiently. The primary advantages of star topology include ease of installation and maintenance, as well as isolation of network issues. If a device fails, it does not affect the rest of the network, and only the connection between that device and the central hub is disrupted. However, if the central hub or switch fails, the entire network is affected because all communication passes through this central point.
