Q66 / 100
What is the difference between "1's complement" and "2's complement" representations of negative numbers?
Correct! Well done.
Incorrect.
The correct answer is A) 1's complement negates a number by inverting all its bits; 2's complement negates a number by inverting all bits and then adding 1, which avoids the dual representation of zero (+0 and -0) that occurs in 1's complement
A
Correct Answer
1's complement negates a number by inverting all its bits; 2's complement negates a number by inverting all bits and then adding 1, which avoids the dual representation of zero (+0 and -0) that occurs in 1's complement
Explanation
2's complement is preferred in most modern systems because it has a single representation for zero and allows addition/subtraction circuits to work uniformly for both positive and negative numbers without special handling.
