Compute the check sum for each of the following data payload. 0x1231 0x0003 0x1232 0xEF23 0X1238 0x4321

Solution

[1].

1231 = 0001 0010 0011 0001
0003 = 0000 0000 0000 0011
----------------------------------
+ 0001 0010 0011 0100 (1234)

[2].

1232 = 0001 0010 0011 0010
EF23 = 1110 1111 0010 0011
1238 = 0001 0010 0011 1000
4321 = 0100 0011 0010 0001
-----------------------------------
+ 0101 0110 1010 1110
+1
---------------------------------
0101 0110 1010 1111 (56AF)
