1) Why can a single binary value represent both a signed integer value and an unsigned integer value? Use a representative example to help your explanation. An example of such a case is the binary value ‘111’. As a signed integer, the most significant bit, ‘1’ makes the value negative in the 2’s complement system. As a result, its value is ‘-1’ in decimal. However, as an unsigned integer, it represents ‘7’ in decimal. 2) For each component supplied in Logisim’s Arithmeti...
