Question

which is the MSB of representation of -80 in sign and magnitude method​

Answer 1

Answer:

For n bits register, MSB will be sign bit and (n-1) bits will be magnitude. ... It means 0 has two different representation one is -0 (e.g., 1 00000 in six bit register) and second is +0 (e.g., 0 00000 in six bit register). 1's Complement Method : Please note that MSB is always Sign bit, if it 0, then there are no changes.
