The range of integers that can be represented by an $n$ bit $2’s$ complement number system is:
$-2^{n-1} \text{ to } (2^{n-1} -1)$
$-(2^{n-1} -1) \text{ to } (2^{n-1} -1)$
$-2^{n-1} \text{ to } 2^{n-1}$
$-(2^{n-1} +1) \text{ to } (2^{n-1} -1)$
An n-bit two's-complement numeral system can represent every integer in the range −(2^{n − 1}) to +(2^{n − 1} − 1).
while ones' complement can only represent integers in the range −(2^{n − 1} − 1) to +(2^{n − 1} − 1).
