Unsigned and Signed Integers

4. Suppose we are designing a computer system and n = 12-bits are allocated for unsigned integers. What is the range, in decimal, of unsigned integers that can be represented? For full credit, explain your answer.

5. In the same system, n = 12-bits are allocated for signed two's complement integers. What is the range, in decimal, of signed integers that can be represented? For full credit, explain your answer.

6. Continuing, what would be the two's complement representation of the decimal integer -1? Write your answer in hex and for full credit, explain your answer.
