Question

The largest integer that can be represented in signed-2's complement representation using n bits is

A) 2n-1

B) 2n)

C) 20-1-1

D) 20-1

Answer 1

Answer : -

❥ Option A

• 2N-1-1

• Two's complement essentially takes one bit away from the value for use as a sign bit. Since we have one fewer binary digit, the maximum value is 1/2 what it would be for an unsigned number with the same number of bits. The largest positive value in N-bit two's complement is 0111... 111, which is 2N-1-1.

Hope it will help you dear!!!
