Q1:

A sign bit of "1" in the difference of a 2's-complement subtraction problem indicates the magnitude is negative and in true binary form.

A True

B False

ANS:B - False

The "1" that comes in the result after one's complement show that the result is -ve. In 2's complement, the 1 is already wrapped and added to the LSB of the result after 1's complement.
