Which of the following representations in two's complement notation represents the largest value?
a)10
b)
c)1
d)0

C

Explanation:

B and D are negative values as they both start with 1, so naturally A and C are the larger values, assuming larger = more positive.

To get the values of A and C which are positive, simply inverse the bits till the last 1 digit. For A, that's 1111 1110 and for C that's 1111 1111. Hence, the magnitude of C is 1*(2^0) larger than A.

its a for sure man enjoy your correct answer

i think the answer is a or d
