    A ____________________ consists of an inner conductor and an outer conductor separated by an insulated plastic.

    • FIBER OPTIC

    • MICROWAVE

    • COAXIAL CABLE

    • TWISTED PAIR

    Correct Answer
    A. COAXIAL CABLE
    Explanation
    A coaxial cable consists of an inner conductor and an outer conductor separated by an insulated plastic. This design allows for the transmission of signals with minimal interference and loss. The inner conductor carries the signal, while the outer conductor acts as a shield, protecting the signal from external electromagnetic interference. The insulation between the two conductors prevents them from coming into direct contact, ensuring proper signal transmission. Coaxial cables are commonly used in applications such as cable television, internet connections, and telecommunications.

    The digital signal is the faster than ______________

    Correct Answer
    ANALOGUE, ANALOG
    Explanation
    Analog signals are slower than digital signals. This is because analog signals are continuous and can have infinite values, while digital signals are discrete and have a limited number of values. In digital signals, information is encoded into binary code, which allows for faster transmission and processing. Therefore, the correct answer is "analog" as it is slower than digital signals.

    Rate this question:

  • 27. 

    An  _____________ signal is a continuous Electric wave.

    Correct Answer
    ANALOG, ANALOGUE
    Explanation
    An analog signal is a continuous electric wave that represents information by varying its amplitude, frequency, or phase. It is used to transmit audio, video, and other types of data. Analog signals are characterized by their ability to have an infinite number of values within a given range, allowing for smooth and continuous representation of data. The term "analog" is often used interchangeably with "analogue" to refer to this type of signal.

    Rate this question:

  • 28. 

    A _______________ consists of two signals, 1 or 0.

    Correct Answer
    BIT, BINARY NUMBER, BINARY NUMBERS
    Explanation
    A bit is the smallest unit of information in computing and can have a value of either 1 or 0. A binary number is a number expressed in the base-2 numeral system, which uses only two digits, 1 and 0. Therefore, both a bit and a binary number consist of two signals, 1 or 0.
