Arduino , timer, crystal oscillator, delay, mills


simple question, arduino has 16.000hrz oscillator.
i got used take time quite precisely.

since i''m making project needs time precision(not really).
is crystal activated or read trough command or allways used delay mills , micros?


thank answer!!sorry noob question.

the answer noobs: every microcontroller (every computer) needs oscillator.
by default it's working (at 16 mhz on arduino uno).

it's used, delays , millis , micros , such functions.
there couple of internal timers, triggered external oscillator, controlling , other internal timing functions.

there incredible tricks possible, not use crystal create oscillations differently, use different fequency, or change how internal timers work.
