    Question

    What is unguided transmission in the context of data communication?

    A Transmission of data over physical cables or fibers using guided media. Correct Answer Incorrect Answer
    B Transmission of data using wireless methods that do not rely on physical conduits. Correct Answer Incorrect Answer
    C Transmission of data over networks using guided waves through waveguides. Correct Answer Incorrect Answer
    D Transmission of data using fiber optics to provide high-speed data transfer. Correct Answer Incorrect Answer
    E Transmission of data through electrical signals over coaxial cables. Correct Answer Incorrect Answer

    Solution

    Unguided transmission, also known as wireless transmission, refers to the method of sending data without the use of physical media such as cables or fibers. This type of transmission utilizes electromagnetic waves to propagate data through the air or space. Examples of unguided transmission include radio waves, microwaves, and infrared communication. In unguided transmission, data is transmitted over the air or through space, relying on radio frequencies, microwaves, or other forms of wireless signals. This method contrasts with guided transmission, where data is sent through physical media like cables or optical fibers. Unguided transmission is essential for mobile communication, satellite communication, and Wi-Fi networks, allowing for greater flexibility and mobility in data communication.
