An atomic clock is a type of clock that uses an atomic resonance frequency standard as its timekeeping element. It is the most accurate type of clock available and is used to set other clocks and time standards around the world. Atomic clocks are based on the oscillations of atoms, which are extremely precise and consistent. They use a frequency that can be measured and compared to an atomic clock to determine time. Atomic clocks are used to power GPS satellites, control telecommunications networks, and to keep time in computers and other electronic devices.
