Explanation / Answer

(According to Chegg policy, only four subquestions will be answered. Please post the remaining in a separate question)

4. The binary representation of 13 is 1101.

This can be written in 7 bits as 0001101

The 1's compliment of 13 is 1110010   

So the 2's complement of 13 is 1110011

To get the 2's complement of -13, append a leading 1

= 11110011

5. The binary representation of 13 is 1101.

This can be written in 7 bits as 0001101

Appending leading sign bit 1

= 10001101

6. The binary representation of 13 is 1101.

This can be written in 7 bits as 0001101

The 1's compliment of 13 is 1110010   

To get the 2's complement of -13, append a leading 1

= 11110010

7. Two alternatives to using Programmed I/O in a computer architecture are Direct Memory Access (DMA) and Interrupt-driven I/O.
