What is Computer? Volume of Bits Even the most sophisticated computer is really only a large,well-organized volume of bits. if this hit Operations fip this bit zero this bit is I.flip this bit 0101 0101 0101 if this b翊 It can normally carry out only a p邮如 zero this bit is1,明 this bit 0100 0101 small number of extremely 0100 simple operations on them,e.g., 01101 0100 1101 zeroing,flipping,and testing Flipping Zeroing Testing 2022/12/14
