A clock is simply an apparatus that counts a repetitive event, e.g. in a mechanical clock, a pendulum might swing once every second and by counting the number of swings, one knows how many seconds have passed. Atomic clocks use atoms, more precisely the electronic transition from one state to another as their ‘pendulum’.
