1. What is the maximum negative 2's complement number that can be represented using a total of 5 bits?

Hint:The two's complement range with N digits is ?(2N???1 ? 1) to +(2N - 1).

-(25???1 ? 1)=-(24 ? 1)=-(16-1)=-15

2. A computer has an mar (memory address register) of 32-bits. What is the size of virtual memory?

32-bit register can address 232 = 4,294,967,296 bytes of memory, or 4 gibibytes (GBytes)

3. A 4-bit two-complement system is in use. What is the range of numbers (in decimal) which can be represented?

Hint:The two's complement range with N digits is ?(2N???1 ? 1) to +(2N - 1).

?(24???1 ? 1) to +(24 - 1).

?(23 ? 1) to +(23).

-7 to +8
