Consider a hypothetical microprocessor generating a 16-bit address (for example assume that the program counter and the address registers are 16 bits wide) and having a 16-bit data bus.

-What is the maximum memory address space that the processor can access directly if it is connected to a "16-bit memory"?

-What is the maximum memory address space that the processor can access directly if it is connected to an "8-bit memory"?

-What architectural features will allow this microprocessor to access a separate "I/O space"?

-If an input and an output instruction can specify an 8-bit I/O port number, how many 8-bit I/O ports can the microprocessors support? How many 16 - bit I/O port? Explain.
