What is the difference between the sign-magnitude and 2's-complement systems of representing signed binary numbers?
A) In the 2's-complement system, all positive numbers are entered in the 2's-complement form preceded by 0 to indicate the sign and all negative numbers are entered in straight binary format preceded by a 1 to indicate the sign. The sign-magnitude system requires that positive and negative numbers be entered in straight binary form preceded by a 0 or 1 to indicate the proper sign.
B) In the 2's complement system all numbers, regardless of signs, are entered in the 2's-complement preceded by a 1 or 0 to denote sign. In the sign-magnitude method, the magnitude bits represent the true binary value and the bit preceding the MSB represents the sign of the following bits.
C) In the signed-magnitude system all numbers, regardless of their sign, are in straight binary format preceded by a 0 or 1 to denote the sign. In the 2's complement system, the negative numbers are entered in the 2's-complement form preceded by a 1 to acknowledge a negative number whereas positive numbers are entered in straight binary format preceded by a 0 to indicate the sign.
D) In the sign-magnitude system all numbers, regardless of their sign, are in the 2's-complement form preceded by a 0 or 1 to indicate their sign. On the other hand, the 2's-complement system requires the sign-magnitude bits be in straight binary format preceded by a 0 or 1 to denote the proper sign.
