Correct understanding of the number in memory high in high, low in low

Look at the example below
Char Szdword[4] = {0x01,0x02,0x03,0x04};
DWORD *PDW = (DWORD *) Szdword;
Array Szdword Four number of permutations of 0x01,0x02,0x03,0x04, their address order from low to high, converted to DWORD *, PDW memory real value is what?
Because the value in memory is high in the high, low in the low, so 0x01 is actually at the far right of the value, because when we read, the right side is the low 0x04 on the left, that is, each byte should be reversed, so pDW the real value is 0x04030201, And they are in memory from low to high order is 0x01,0x02,0x03,0x04
