1) If CS = 25H then find the second and second to last physical address of this segment.
2) Suppose you want to design a Microwave and are in need of a processing unit. Would you choose to use a microprocessor or a microcontroller for this purpose? Explain with logic.
3) “The data bus is bidirectional but the address bus is unidirectional”
