Designations R, C, D, on the memory card, what do they mean?

Question

Electronics

On a flash drive, Designations R3, R5, R1, R12C3, C1, C4, C8, C10, D2, D3, D4, D5 and adjacent elements with inscriptions, what are they called? And their approximate purpose ..

On the reverse side, black, what is it?

In a simpler and more competent way, if possible, please.)

Answer 1

R - resistor
C - capacitor
D - diode
Black crap - microcircuit.

Answer 2

Radio components, elkin root :) (R) Resistors, (C) Capacitors and (D) Diodes. Black crap from the "front" side is the controller chip, from the "back" side is the memory chip. Flash drive gutted? :) The purpose of radio components is to work as elements of a radio circuit :) In this case, a passive strapping for chips. If you google - maybe you will find a diagram of this flash drive - where all the elements are indicated in the same way as on the board (more precisely, on the contrary - on the board, as on the diagram, because the circuit is primary).
