What aspect of a Von Neumann Architecture makes it more vulnerable to hackers than a Harvard Architecture? 3. If the arithmetic hardware on a computer requires operands to be in separate banks, what instruction sequence will be needed to compute the following? A B - C Q A * C W Q + A Z W - Q 4. A computer architect boasted that they were able to design a computer in which every instruction occupied exactly thirty-two bits. What is the advantage of such a design?
