How many bits does it take to store 256 in binary? Each byte can only hold 8 bits, and the max number of 8 bites can hold is 255, so for 256, there should be 2 byte which is 16 bites. When a processor computes an addition that has more result bits than the computer supports, it ignores the extra bits. For example, 255+5=4 on an 8-bit processor. This is called overflow. Explain how overflow makes Two's Complement numbers act negative. | I
