    Is a type of clock that displays the time digitally as opposed to an analog clock, where the time is indicated by the positions of rotating hands.

  • Atomic clock

    Atomic clock
    Is a clock device that uses an electronic transition frequency in the microwave, optical, or ultraviolet region of the electromagnetic spectrum of atoms as a frequency standard for its timekeeping element. Atomic clocks are the most accurate time and frequency standards known.
