Explanation:
Detailed explanation-1: -For example, an 8-bit unsigned number can represent the values 0 to 255 (11111111). However a two’s complement 8-bit number can only represent non-negative integers from 0 to 127 (01111111), because the rest of the bit combinations with the most significant bit as ‘1’ represent the negative integers −1 to −128.
Detailed explanation-2: -Detailed Solution. The Correct Answer is-128. The smallest integer that can be represented by an 8-bit number in 2’s complement form is-128.
