I suspect these terms mean what you choose them to mean. Here is what
Google has to offer:
(includes both "number of digits" and "degree of refinement")
(includes "measure of accuracy or dynamic range of an A/D or D/A
converter" and "smallest quantity that can be measured").
>From this, I would suggest:
precision - degree of correctness
resolution - accuracy of measurement
Perhaps NTP has its own definitions?
