8. In a computer, what is a bus, and what does it connect?

9. What is the maximum directly addressable memory capacity in bytes, if the address bus is 16-bit? Assume each memory location is one byte.

10. Consider a hypothetical 32-bit microprocessor having 32-bit instructions composed of two fields, the first byte contains the opcode and the remainder is the operand address.
