1.Select any two decimal numbers between -60 and +60. One should be positive and the other should be negative.
Convert the numbers into 8-bit unsigned numbers with negative numbers in the 2’s complement form. (Remember that positive numbers have the leftmost bit =0 and negative numbers have the leftmost bit =1).
Add the two numbers together to generate an eight-bit binary result. After that assume that the last operation performed on a computer with an 8-bit word was an addition. Show the two 8-bit words being added and the result.
Using this addition:
What would be the value of the following flags?
• Carry
• Zero
• Overflow
• Sign
• Even Parity
2.Does RISC provide better performance today than CISC?
Provide the references you used to support your position.

+60 in 8-bit Two's Complement format is the same as unsigned binary,so we convert as usual and get: 00111100.
For -60 we have:
First 60 in binary is, as above, 00111100.
Now we make the complement, by transforming 0->1 and 1->0. We get 11000011.
In the end we add 1 (for sign bit) and we get 11000011 +1 =11000100.
Now we have to add a positive number (+60) with a negative number (-60)....
