2's complement of 11001011
To find the 2's complement of a binary number, we have to first find the 1's complement (flipping all the bits) and then add 1 to the result.
- 1's complement of 11001011
- The 1's complement of 11001011 is obtained by flipping all the bits: 00110100
- Adding 1 to the 1's complement
- To get the 2's complement, we add 1 to the 1's complement:
00110100
+ 00000001
00110101
Therefore, the 2's complement of 11001011 is 00110101, which corresponds to option C.
