Screen resolution, dp and ppi

Self-tutoring about technology: the tutor inquires about screen size, resolution, dp, and ppi.

Apparently, dp is 160x(screen size in inches).

Resolution means, as I understand, the logical, rather than physical, linear elements across the screen. The reason: ppi (pixels per inch, aka pixel density) is device-dependent.

Resolution may be given in px by px: for example, 1280 by 768 pixels.

To get dp, a formula is (resolution/ppi)*160.
