Explanation:
Detailed explanation-1: -How does binary work? The 0s and 1s in binary represent OFF or ON, respectively. In a transistor, a “0” represents no flow of electricity, and a “1” represents electricity is allowed to flow. This way, numbers are physically represented inside the computing device, permitting calculations.
Detailed explanation-2: -If the number is negative then it is represented using 1’s complement. First represent the number with positive sign and then take 1’s complement of that number. (ii) Take 1’s complement of 0 0101 and that is 1 1010. MSB is 1 which indicates that number is negative.
