    Question

    Which of the following statements accurately describes

    a guided transmission medium?
    A A guided transmission medium does not have a defined path and relies on broadcasting signals through the air. Correct Answer Incorrect Answer
    B A guided transmission medium uses a physical pathway to direct the signal from the sender to the receiver. Correct Answer Incorrect Answer
    C A guided transmission medium is a wireless communication system that transmits data using satellite signals. Correct Answer Incorrect Answer
    D A guided transmission medium involves the use of optical fiber for transmitting data through space without a physical connection. Correct Answer Incorrect Answer
    E A guided transmission medium allows for data transmission over the internet using radio waves. Correct Answer Incorrect Answer

    Solution

    Guided transmission mediums are communication channels that have a defined physical path for the transmission of signals. These mediums include cables and wires such as twisted pair cables, coaxial cables, and optical fibers. The physical pathway ensures that the signal is directed along a specific route from the sender to the receiver, providing a controlled and reliable means of communication. This contrasts with unguided transmission mediums, such as radio waves or satellite signals, which broadcast signals over the air without a defined path. The use of guided transmission mediums helps in reducing signal loss and interference, improving the overall quality and efficiency of data transmission.
